Players keep reporting a recurring cursor problem in Rainbow Six Siege: the mouse pointer gets stuck, disappears, drifts off aim, flickers, or becomes unresponsive in menus. If you’re seeing it again, don’t assume it’s your hardware—this bug is usually tied to focus, display mode, scaling, or an overlay interfering with input.
This guide is written like a field manual: identify the symptom, apply the highest-success fixes first, then move to advanced checks if the issue persists. Follow the steps in order so you don’t waste time chasing random settings.

What the Rainbow Six Siege cursor bug looks like
The “cursor bug” can mean different things depending on the build and your setup. The most common reports fall into these buckets.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitches- Cursor disappears after alt-tabbing or when opening menus (sometimes only in-match).
- Cursor stuck in place while the character keeps moving or aiming.
- Double cursor / delayed cursor behavior where UI click targets feel misaligned.
- Menu navigation works but in-game mouse is wrong (or vice versa).
- Cursor flickers when moving between desktop and full-screen windows.
- Mouse movement becomes “captured” incorrectly after changing settings like resolution or display mode.
If you can, note when it starts: right after a game update, after switching monitors, when using borderless/fullscreen, or immediately after launching Ubisoft Connect or a capture/overlay tool.

Why the cursor bug happens (common causes)
Siege is sensitive to input capture and how Windows treats fullscreen windows. The recurring nature usually points to one of these categories.
- Display mode conflict: Fullscreen vs borderless can change how input is captured and how the cursor behaves.
- Windows scaling / DPI mismatch: 125%/150% scaling or mixed-DPI monitors can break UI-to-pointer mapping.
- Overlay or capture tools: Discord overlay, GeForce Experience/ShadowPlay, Xbox Game Bar, Steam overlay, Overwolf, screen recorders.
- GPU driver regression: A driver update can introduce input or cursor issues in DirectX fullscreen modes.
- Corrupted or mismatched game config: Settings stored in the user profile can get out of sync after patches.
- Windows pointer enhancements: Some “enhancement” features can interfere with raw input expectations.
Before you change anything: prerequisites and quick checks
These checks take minutes and prevent chasing ghosts.
- Confirm your mouse works elsewhere: test in Windows desktop, a browser, or another game.
- Check for background apps: close overlays/capture tools you don’t need.
- Know your display setup: single monitor or multi-monitor, and your current scaling (e.g., 100%, 125%, 150%).
- Write down your current Siege settings: resolution, fullscreen mode, V-Sync, and any input sensitivity values.
Then proceed with the fixes that address the most frequent causes: focus, display mode, and overlays.

Fixes to try first (highest success rate)
Start here. These changes usually fix cursor issues without requiring edits or driver rollbacks.
Restart the game with proper input focus
Cursor issues often persist after alt-tabbing. Do a clean restart and ensure Siege receives focus from the moment it launches.
- Fully close Rainbow Six Siege.
- Quit Ubisoft Connect (system tray) and reopen it.
- Launch Siege and do not alt-tab during the loading screens.
- Test movement and UI navigation in the main menu first.
Switch display mode (Fullscreen ↔ Borderless)
This is the most common fix for cursor problems tied to window capture. If you’re on one mode, flip to the other, then test again.
Rank #2

- Lightweight, Classic fit, Double-needle sleeve and bottom hem
- Open Siege settings.
- Go to Video (or Graphics).
- Change Display Mode between Fullscreen and Borderless.
- Apply and restart the game if prompted.
- Check whether the cursor behaves normally in both menu and in-match.
Practical pairing: if you use multi-monitor or alt-tab often, borderless tends to behave more consistently. If you want raw fullscreen performance, fullscreen can work once overlays and scaling are corrected.
Change DPI scaling and Windows mouse settings
If the pointer doesn’t line up with clicks—or clicks land “off” by a few pixels—Windows scaling is a frequent culprit.
- Right-click your desktop → Display settings.
- Find Scale and set it to 100% (test at 100% even if you prefer 125% in general).
- Under Related settings, open Advanced scaling settings.
- Turn off any custom scaling you’ve configured for apps unless you absolutely need it.
- Restart Siege after changing scaling.
Also check mouse speed features:
- Open Control Panel → Mouse.
- Set Pointer options to a default-like state: disable enhancements such as Snap to items and Enhance pointer precision if it’s on.
- Test again in Siege.
Disable overlays and capture tools
Overlays inject themselves into the game window. When they hook input, the cursor can desync or stop responding.
Disable these one by one (or as a group), then restart Siege:
- Discord overlay (User Settings → Game Overlay).
- Xbox Game Bar (Settings → Gaming → Xbox Game Bar).
- Steam overlay (Steam → Settings → In-Game → uncheck).
- GeForce Experience ShadowPlay / Nvidia overlay.
- RivaTuner / MSI Afterburner OSD.
- Overwolf and similar capture/overlay apps.
If you need one recording tool for clips, test with only that tool enabled. The fastest way to fix is to identify the single offender.

Update or roll back GPU drivers
Cursor behavior in fullscreen DirectX can regress after a driver update. Two paths work: update to the latest stable driver, or roll back to the last known-good version.
- Identify your GPU model (Device Manager → Display adapters).
- Check current driver version in the same menu.
- Install the latest driver for your GPU from the manufacturer.
- If the bug started after a specific update, roll back to the previous version.
After changing drivers, reboot Windows and test Siege immediately before installing any overlays again.
Verify game files in Ubisoft Connect
A damaged config or asset can cause odd UI behavior. Ubisoft Connect has a built-in verify step.

- Go to Games → find Rainbow Six Siege.
- Select Properties or Manage (wording varies slightly by version).
- Choose Verify files.
- Wait for completion, then restart Siege.
Reset Siege video/input settings
If a patch left your config in a weird state, a reset often restores normal cursor/input mapping.
- In Siege, open Settings.
- Find Video and restore defaults for resolution and display mode.
- Go to Controls and reset any unusual input-related changes (especially controller-to-mouse mappings if you touched them).
- Apply changes and restart Siege.
If the game doesn’t offer a clean “reset to defaults,” consider the config reset option in the next section.
Disable Windows pointer enhancements and raw input conflicts
Some mouse software and Windows features can conflict with how Siege expects input.
Rank #4
- Master stealth and strategy with the legendary Rainbow Six Siege Caveira.
- OFFICIALLY LICENSED UBISOFT GEAR
- Lightweight, Classic fit, Double-needle sleeve and bottom hem
- In mouse driver software (Logitech G Hub, Razer Synapse, SteelSeries GG), disable any “enhanced” pointer features temporarily.
- If you have custom profiles per app, remove Siege from that profile and test with a generic default.
- Disable “acceleration” and any smoothing filters during testing.
Then launch Siege and test cursor behavior in menu and match.
Edit user settings to force safer defaults
If your cursor bug persists after video/input reset, you can reset the user config by reverting to a clean settings state. The exact file location depends on your installation and patch era, but the principle is consistent: remove or rename the user settings file so Siege regenerates it.
- Locate Siege user settings in your Windows profile (commonly under
Documentsor the game’scache/configfolders). - Rename the settings file (e.g., append
.bak) rather than deleting it. - Launch Siege; let it recreate default settings.
- Reapply only the essentials: resolution, display mode, and your preferred sensitivity.
After testing, you can restore the original file if needed—but keep a known-good baseline so you can identify which change triggered the cursor issue.
Platform-specific guidance (Windows)
Windows 10/11: fix focus, scaling, and overlays
Most cursor bugs show up on Windows because window management and DPI scaling directly affect how cursor coordinates map to UI elements.
- Check Windows scaling: set Scale to 100% for testing.
- Disable overlays: Discord, Xbox Game Bar, Steam overlay, GeForce/Nvidia overlay, screen recorders.
- Toggle display mode in Siege: try Fullscreen first, then Borderless.
- Reboot after driver changes or major overlay changes.
- Test in order: menu cursor first, then entering a match to verify in-game behavior.
If you use a mixed-DPI multi-monitor setup, treat that as a suspect: unplug the second monitor temporarily and retest with only one display connected.
Troubleshooting checklist when the main fix fails
Use this as a fast diagnostic flow. Each step targets a different failure mode.
Best Value
- Etched By Hand
- Try a clean Windows boot: disable non-Microsoft startup apps and retest Siege.
- Test with one monitor: disconnect extra displays to remove scaling and focus complexity.
- Change refresh rate: in Windows Display settings, temporarily set a common rate (e.g., 60 Hz) and retest.
- Disable all mouse software temporarily: close Logitech/Razer/SteelSeries apps and test.
- Reinstall Ubisoft Connect (rare): if verification and config reset fail, the launcher components may be stale.
- Try a different Windows user account: helps identify corrupted user profile settings.
Once it works, re-enable apps one at a time so you know what caused the regression.
Common mistakes that keep the bug coming back
- Changing multiple settings at once (you’ll never know which one fixed it).
- Leaving an overlay enabled during testing (Discord + Game Bar together can trigger strange input capture).
- Assuming fullscreen settings alone matter without addressing Windows scaling.
- Skipping a full restart after driver changes—some input hooks don’t unload until reboot.
- Not retesting both menu and in-match. Cursor problems can behave differently per window state.
Comparison: which fixes help which symptoms
If you want to be efficient, match your symptom to the most likely fix.
| Symptom | Most likely cause | Best first fix |
|---|---|---|
| Cursor disappears after alt-tab | Focus/window capture conflict | Switch Fullscreen ↔ Borderless, then restart Siege |
| Clicks land “off” / UI feels offset | DPI scaling mismatch | Set Windows scaling to 100% and retest |
| Cursor flickers when moving between desktop and game | Overlay/capture hook | Disable Discord overlay + Xbox Game Bar |
| Cursor stuck while aiming/moving continues | Input hook regression or config corruption | Verify files, then reset video/input settings |
| Everything works until you enable screen recording | Capture tool injection | Keep only one capture tool enabled; test each |
| Issue began right after GPU driver update | Driver regression | Roll back to previous driver |
FAQ
Why does the Rainbow Six Siege cursor bug happen after updates?
Updates can change how Siege handles fullscreen window states and UI scaling. If your setup is already sensitive (multi-monitor scaling, overlays, custom mouse software), the patch can make the conflict show up again.
The Tool Desk
Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →Does using Borderless vs Fullscreen affect cursor behavior?
Yes. Many cursor issues are tied to how the game captures input in fullscreen DirectX versus borderless windowed mode. If fullscreen breaks your cursor, borderless often restores stable behavior.
Will verifying files fix a cursor-only problem?
It can. If the bug is caused by a corrupted setting/config file, verification may restore expected defaults. It’s also a low-risk step compared to driver rollbacks.
Are controller settings related to a mouse cursor bug?
They can be. If your controls were changed and a patch altered input handling, mismatched mappings can cause UI navigation and cursor capture problems. Reset controls to defaults if you’ve been experimenting.
What if none of this works?
Collect your “before and after” data: your Windows scaling value, display mode, driver version, and which overlays were enabled. Then try a clean Windows boot and test with only one monitor connected. If it still fails, it’s likely a specific compatibility issue you’ll need to track with exact system details.

The Rainbow Six Siege cursor bug isn’t usually a dying mouse. It’s most often a window focus problem, DPI scaling mismatch, or an overlay/capture tool interfering with input capture.
Start with display mode (Fullscreen ↔ Borderless), then disable overlays, then fix Windows scaling to 100% for testing. If it began after a driver update, roll back. Once you find the trigger, keep a clean baseline so the same setup doesn’t quietly re-break every time Siege patches.
