I decided to record how my system behaves when using Linux and my 390 together.
This is what I see https://www.youtube.com/watch?v=9uVIzHFlTZk
This is Ubuntu MATE 16.10 with Firefox open¹, something that is not at all graphically intensive. On KDE Plasma 5 it's even worse, my entire system will sometimes crash. It's completely unusable and I'm stuck on Windows because of this.
¹ I know there is a tab that says "Chrome Experiments", but it's unloaded. I tried loading one to see what would happen if I tried something a bit intensive, but my entire system crashed. Ended up having to restart recovered my session in Firefox.
This look the same for other 390 users?
thanks for the video maybe I should open another bug, I have the same artifacts with a rx460. It happens randomly when resuming from standby, similar symptoms as described in this bug. I will try patching the kernel and disabling some dpm features as suggested, I'm not sure if it started happening with 4.9 or 4.10. Setting power_dpm_force_performance_level to manual or high doesn't work.
