--- Comment #182 from Chris Heald <cheald@gmail.com> ---
Just adding a data point here, I've got an MSI R9 390 running on Ubuntu 18.04
on 4.15.0-10-generic - I haven't had any stability issues, but I have had
maddening screen flickering/corruption.

I'm running dual 2560x1440 monitors off the card, which forces the memory clock
to 1500MHz. However, when the GPU clock is at the 300MHz level, I get
horrendous artifacting any time an accelerated portion of the screen is drawn.
I can easily reproduce the issue by mousing over certain KDE widgets which are
acclerated. Interestingly, running glxgears doesn't cause the issue.

* Setting power_dpm_force_performance_level -> high fixes it (but runs the
clock up to its max, obviously)
* Setting power_dpm_force_performance_level -> manual and then `echo 1234567 >
pp_dpm_sclk` fixes it, with the GPU clock fixed to 500MHz.

I've been up and down this issue with both radeon and amdgpu drivers; neither
seems to make a difference.

        Kernel driver in use: amdgpu

# cat vbios_version

(Interestingly, this BIOS is newer than anything on techpowerup. I was hoping a
BIOS flash would fix it, but I can't find anything newer)

I'll attach dmesg and Xorg logs as well. If I can provide extra data points,
I'd like to help.
