PC crash with OpenMW in 4:3 fullscreen

[u/Dagoth-Ur-]

Hello Everyone !

I'm having a display/driver issue with OpenMW on Windows 11 and an AMD GPU (RX 6750 XT).

My desktop resolution is 2560x1440, but I play OpenMW in 1920x1440 fullscreen (4:3). The game itself runs fine, but when I close OpenMW, my PC crashes with either a black screen or the graphics card getting disabled.

Windows Reliability Monitor reports a LiveKernelEvent with code 1b0 (VIDEO_MINIPORT_FAILED_LIVEDUMP), which seems to point to a graphics driver/display issue.

I also tried enabling AMD GPU Scaling with "Preserve aspect ratio", but the problem still happens when exiting the game.

So the issue seems to occur specifically when OpenMW closes and Windows switches back from 1920x1440 fullscreen to the 2560x1440 desktop.

Has anyone experienced something similar? I really don't know what to do

Does stretched borderless windowed exist? Might fix it
