Luckily I only have good news, as we've actually been looking into this issue for a bit now and have made a pretty good amount of progress. There's pretty much only one issue left for us to fix I'm fairly sure: https://gitlab.freedesktop.org/drm/amd/-/issues/2171 If you'd like to help, there's some logs I could use someone getting to help me figure out the last remaining issue here.
