-- Information about the crash:
Good day,

While trying to play some games on my dell alienware x16 r2 (core ultra 9 185h
and 4090 mobile) with nobara linux version 44 with kernel 7.1.6,  my device
completely crashes and brings me to kwin to report the bug. 

This is my proton configuration:

mangohud PROTON_ENABLE_NVAPI=1 PROTON_ENABLE_NGX_UPDATER=1 PROTON_NVIDIA_LIBS=1
gamemoderun LD_PRELOAD="" SCB_AUTO_HDR=1 SCB_AUTO_RES=1 scopebuddy -f -r 240 --
%command%

I got this bug whether I used GE-Proton 11.2, dwproton 11.0-11, cachyos
11.0-20260703 or other proton versions.

The crash can be reproduced every time.
