[Wayland Backend] KWin-Wayland scaling values other than 100% along with --force-grab-cursor cause Dx11/Dx12 games to crash when cursor goes to the bottom or right edge of screen.

Is there an existing issue for this?

[X] I have searched the existing issues

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

[X] The issue occurs on upstream gamescope without any modifications

Current Behavior

Currently, some games require the --force-grab-cursor to correctly function. In my case this game is Planet Coaster 2 through Steam / Proton Experimental. Others have reported God of War as also exhibiting this issue.

However, this argument appears to also be bugged in instances where the Kwin-wayland scaling factor is !=100% causing an even worse issue - the game outright crashing when the cursor reaches the right or bottom edge of the screen.

I cannot reproduce this with glxgears or vkcube, so this does not appear to be an issue with native OpenGL or Vulkan games/runtimes and likely only impacts DirectX titles.

This issue resembles https://github.com/ValveSoftware/gamescope/issues/1434, but is different in that:

Using -b or -f does not mitigate the issue. In the original post it did.
Using --force-grab-cursor does not work as expected. In the original post it did.

In a way this issue is almost the inverse of Issue #1434 .

Steps To Reproduce

Set KDE to a display scaling factor that is not 100%. It can be in either direction.
Install Planet Coaster 2 from Steam using Proton Experimental
Update the arguments to gamescope -W 3840 -H 2160 --hdr-enabled --fullscreen --force-grab-cursor -- %command% - updated to your native resolution, of course.
Launch the game.
Once the game loads move your cursor to the far right, or to the bottom of the screen.
Gamescope instantly crashes and exits.

I see the same crash in Planet Coaster 2 on my 7900XTX with Plasma 6.2.3. Poked at it a bit and grabbed what I could for debugging.

Interestingly, I only started experiencing the issue once I set a 4K or higher resolution like you gave in your command. If I use -W 1920 -H 1080 or -W 2560 -H 1440 or -W 1280 -H 800, then the crash doesn't occur.

Display (SAM7474): 7680x2160 @ 240 Hz (as 5120x1440) in 57" [External] [HDR] is how my monitor gets reported with 150% scaling in KWin. If I set -W 5120 -H 1440 then the crash does not occur, while if I set my monitor's true resolution with -W 7680 -H 2160 then the crash does occur.

coredump from a crash at 7680x2160p here:
