A770 4K blinking artifacts and [drm] *ERROR* Fault errors on pipe B: 0x00000080
Since I moved from 1080p monitor to 4k 160hz I started getting weird glitches like black rectangles for a few frames in the right bottom corner by 1/4 size of my screen or by size half my screen on the right side when playing games. Sometimes I get blinking lines on top. The dmesg only says Fault errors on pipe B: 0x00000080
The thing is that it all is almost completely gone when I switch to 1440p resolution.
Another problem I stumbled upon is a completely black screen when I select 4k 160hz mode, so currently I'm limited by 144hz. The same mode works perfectly in Windows. I think that might be related to Display Stream Compression, since its required for these high settings for dp1.4.
PS I don't know now to name that issue, feel free to rename.
My system. I know it shows 1080p, its because of 200% scaling. The monitor is KTC M27P20 Pro
