My friend and I have an issue where when we play games trough proton and some even native (Cs2) that when we tab into the game that the mouse stays unlocked and moves to another monitor.

Causing us to click out of the game by accident.

Is there any way to fix it without gamescope?

KDE Plasma 6.7.4 (Wayland)

Try switch in the game from"Window Fullscreen" to “Fullscreen”.
