 # Known Issues
 
-## SteamVR: laser pointers not visible
+## Modifiers get stuck in weird ways
 
-This seems to be a rare issue with SteamVR startup overlays. Restarting the overlay will fix the issue.
+This is a rare issue that can make your desktop not react to click or keys due to a modifier being stuck somewhere. Restarting the overlay fixes this.
 
 ## Scroll wheel doesn't work
 
 This seems to be an issue specific to Electron apps (Discord, Element, Slack, Spotify) on Wayland. Scrolling will work when using these in your web browser.
 
-## WiVRn support
-
-While WiVRn technically supports EXTX_overlay, I do not recommend using this software with WiVRn at this time, due to WiVRn not being optimized for overlay apps. You will likely get ghosting or stuttering while rotating your head.

 ## X11 limitations
 
 DPI scaling and upright screens are not supported on X11. These might display incorrectly or mess up your mouse position.
