Commen= t # 9 on bug 11019= 9 from Eduardo Saporski 
Can confirm. My GPU is MSI RX580 Armor 8G OC and my monitor As=
us VP247QG
(FreeSync, 48Hz to 75Hz).

I'm on Solus 4 using the open source drivers (POLARIS10 DRM 3.27.0
5.0.5-113.current LLVM 7.0.0, OpenGL version 4.5, Mesa 19.0.0) and the
flickering is exactly like Maxim showed.

The workaround is setting DPM to high:
"echo 'high' > /sys/class/drm/card0/device/power_dpm_force_performa=
nce_level"
