i recently upgraded to a 1440p 144Hz display connected to a RX 480 8GB GPU via displayport 1.2.
When i use 144Hz i get artifacts on the upper 3-5% of my display area. However when i change to 120Hz the artifacts are gone.
Any ideas what could cause that troubles?
i use the AMDGPU driver and xfce4 with xfwm
