Hi. I’m experiencing stutter issues when using Plasma 5 with composition on AMDGPU (RX 570) with FullHD 60p display. This stuttering is very apparent with 1080p60 videos as this or while autoscrolliing in Firefox. As per this issue kwin is skipping frames with default frame rates settings. Manually setting RefreshRate=61 and MaxFPS=61 in ~/.config/kwinrc solves this stuttering problem, but introduces input latencies for dragging windows.
Xrender works fine but with tearing. Setting Option “tearfree” "true solves tearing but now moving cursor or windows on 1080p60 content causes stutter too.
Is there any way to sync both display and compositor`s OpenGL backend to using 60 fps?
