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?
Putting the laptop in the fridge and cooling it down makes it work. Hardware defect seems confirmed.
