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. ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1844580 Title: Screen tearing with AMD open source drivers and a high refresh rate monitor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1844580/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
