If I add the bluecherry user to the render group and restart bluecherry, I see BUG: Segment violation at 0x000075a26d981310 in the logs below. If I remove bluecherry from the render group, it works as expected so it seems VAAPI specific. This is on ubuntu 24.04.1 on an Intel Core i5-14500 (14th gen Raptor Lake) with no other GPU.
Bluecherry is version 3.1.3.
