--- Comment #33 from Mike Bendel <> ---
I'm also experiencing the same issues, but on much lower refresh rates. I have
a 3840x1600 monitor (LG 38UC99) and when running at 75Hz, display corruption is
observed on both AMD GPUs I have, a Radeon Pro WX 5100 and Radeon RX 550.

Fortunately, setting the power level to high makes the display corruption go
away entirely, but also raises temperatures substantially. The idle temp on my
WX 5100 gets up to 60 C by doing that.

Is there a way to lower the clocks in the high performance state? I know some 
utilities like MSI Afterburner allow for this in Windows, but I'm not sure how
to do it on Linux.
