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. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu7 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: apolihron 1196 F.... pulseaudio /dev/snd/controlC0: apolihron 1196 F.... pulseaudio CurrentDesktop: MATE DistroRelease: Ubuntu 19.10 InstallationDate: Installed on 2019-08-27 (22 days ago) InstallationMedia: Ubuntu-MATE 19.10 "Eoan Ermine" - Alpha amd64 (20190827) IwConfig: lo no wireless extensions. enp31s0 no wireless extensions.
