[Desktop-packages] [Bug 1813701] Re: [amdgpu] Flickering graphics corruption (but none observed in kernels 4.18.10-4.18.12)

[Drew Walton]

The issue is somewhere in the dynamic power management code. Here's a
workaround that has completely resolved the flickering (for me):

As root:
echo "high" > /sys/class/drm/card0/device/power_dpm_force_performance_level

Title:
  [amdgpu] Flickering graphics corruption (but none observed in kernels
  4.18.10-4.18.12)

Status in linux package in Ubuntu:
  Confirmed
Status in xserver-xorg-video-amdgpu package in Ubuntu:
  Confirmed

Bug description:
  The screen always flickers at a frequency of 75 GHz on the AMD RX 580 gpu. At 
60 and 50 GHz, if you switch to any other than 75, the flickering will 
disappear until the display turns off. After switching on, flicker returns. At 
the core of 4.18.0-10, just like on the AMD Radeon HD7970 gpu, the problem is 
not visible. More in the video
