Yes I had been experimenting with kernel flags trying to fix it. I had it 0
before and it was happening too. Also have tried that variation with
amdgpu.dc=0 and 1, the one with update_mode=1 only with amdgpu.dc=0

No Core OpenGL apps too. Hadn't had it happen to legacy OpenGL apps yet (or any
wine DirectX app actually, not sure if they use core or legacy), but that of
course doesn't mean it couldn't happen there too.
