Mouse gets stuck on right edge and snaps back when moving left

[TheOwn68]

Is there an existing issue for this?

• I have searched the existing issues

Are you using any gamescope patches or a forked version of gamescope?

• The issue occurs on upstream gamescope without any modifications

Current Behavior

When running games through Gamescope on KDE Wayland, the mouse sometimes becomes stuck on the right edge of the screen.
When I try to move the mouse left, the pointer teleports back to the right side instantly.

Steps To Reproduce

1. Launch Meccha Chameleon or R.E.P.O through Gamescope
2. Move the mouse to the left
3. The mouse becomes stuck on the right side
4. Attempting to move left causes the pointer to snap back to the right immediately
   This does not happen outside Gamescope
