Screen tearing between tiles on 5k tiled dual DP displays
Follow up to #27 (closed)
Now that 5K tiled displays are fully supported in 5.9, I noticed is that there is very noticeable screen tearing between the two tiles when playing video with a lot of motion, while there is none in Windows. I've been seeing this since 5.8 + @vsyrjala's EDID parsing patch enabled the LG 5K monitor to run at native 5K resolution, and still see it in 5.9 on both Fedora and Gentoo. Is there anything that can be done to eliminate the tearing like Windows does? It's pretty distracting when watching YouTube or Netflix, so it would be great if it could be fixed. Thanks!
Here's an example video showing this while playing YouTube fullscreen: https://photos.app.goo.gl/h9j3FRetYLkBaWzR7
