Bug Description
Just did a fresh install of Ubuntu 20.04 LTS and everything was fine, display worked perfect. Then I put the machine in Suspend mode (by clicking on GUI button), left for 5 minutes, came back, woke up the machine (by clicking a key on the keyboard), and upon waking up, the display started flickering heavily.
Relevant Specs (Sorry if I missed anything):
AMD® Ryzen 9 3900x 12-core processor × 24
AMD® Radeon rx 5700 xt
GNOME version 3.36.1
Windowing System X11
I am running 3 monitors: Samsung with resolution 3840x2160 and 2 LG monitors with resolution 1920x1080, all at 60Hz
Most of the flickering is happening on Samsung, although once in a while, other monitors flicker a little bit as well.
Things to note: When I switch Samsung to lower resolution, the flickering goes away. When I come back to 3840x2160, it comes back. When I switch to lower resolution, suspend and come back, everything is fine.
If I reboot the machine, the display is fine until I suspend and wake up again (if I am in higher resolution).
I tried changing the refresh rate of Samsung to 30.00 and 29.97 (the only two available when I turn off FreeSync), and the issue still persists. Turning FreeSync on and off does nothing.
Thank you,
Pavel.
