It seems like I’m the only person on the planet with this problem, but on a fresh install of Windows 11 with the latest drivers on a Framework 13 AMD 7640U, I am unable to play back video. The graphics driver crashes, sometimes so spectacularly that it hard-resets the computer. Playback works fine on Fedora 39, so I assume the hardware is fine.
Does nobody run Windows on these laptops?
VLC, Firefox, Chrome, some random other viewer I downloaded - they all have the same behavior on Windows.
VLC on Fedora seemed to work.
