[Bug 96868] AMDGPU Tonga only does 2560x1440 at 120hz, switching to 144hz causes display errors, same thing used to happen with fglrx.

--- Comment #12 from iuno at posteo.net ---
Yeah, forcing high clock rates seem to fix the flickering issue.

The problem is actually the memory clock. However, today, without my
intervention, the memory clock stays at max (1250 MHz) for high refresh rates,
while the core clock still goes down to 300, as it should. So this god "fixed"
indeed.

I still have the 144 Hz problem with corrupt image, though.
