Public bug reported:
i have the following issue:
If i use a monitor with a higher refresh rate then 60 then i will get nasty
screen tearing and flickering.
I have a monitor with 75 hz ,a amd rx 480 gpu with open source video drivers.
The work-around the issue that i found is to force the gpu power state to high
with the command echo high >
/sys/class/drm/card0/device/power_dpm_force_performance_level
In my opinion this should be a High importance because it will offer a pour
experience when for every user that it's using open source drivers and a high
refresh monitor
Tested on Ubuntu and Ubuntu Mate 18.04.x ,19.04 and 19.10 daily.
