Please attach the corresponding Xorg log file and output of dmesg. Created attachment 143724 [details] [review] 0001-drm-amd-display-Only-allow-VRR-when-vrefresh-is-with.patch I think this patch should fix your issue. We previously blocked enabling it if vrefresh < min supported range, but we didn't cover vrefresh > max supported range. > I think this patch should fix your issue
Indeed it does, thanks! :)
I've seen it is already in for 5.1. Don't you think it should be backported for 5.0 as well? I'm not sure if the issue could damage the display but for what I can tell, it's a serious bug and surely looks disturbing to users.

Created attachment 143688 [details] raw edid Hi, my monitor has a FreeSync range from 35 to 90 Hz. The maximum supported refresh rate is 144, which I use by default. When switching mode to a refresh rate >90 (120 or 144), the monitor's HUD says that FreeSync is now disabled. On Windows, this is the case. However, VRR is still being enabled with 144 Hz on Linux 5.0, mesa 19 and xf86-video-amdgpu 19. It results in heavy artifacts, the timing is broken so that even the monitor HUD is broken. I've attached the monitor's EDID. Regards
