Cant load saved game; system locks up, screen flashes funny colours

[Falc]

I'm installed OpenMW on PopOS 21.10. When I start OpenMW and load a saved game or start a new game the screen flashes between black, normal colours and weird purple / yellow / white colours. The whole system locks up and I need to do a hard reset.

I don't get any terminal error messages so I'm not sure where to begin debugging this. Any idea what could be causing this? Its almost like a driver error then just completely crashes my system, but is only caused by OpenMW.

That definitely sounds like a graphics driver issue to me. An application shouldn't have the ability to completely crash the system, but a sufficiently broken driver definitely does. It's probably possible to trigger it without OpenMW if you've got another application that makes the same sequence of calls that trigger the bug, but obviously different applications make different calls as they want to draw different things.
