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?
My 7840 win11pro has no issues, what are you using to playback with? Or do you mean YouTube in which case have you done all the usual cache flushing and browser swapping stuff?
VLC, Firefox, Chrome, some random other viewer I downloaded - they all have the same behavior on Windows.
VLC on Fedora seemed to work.
