Hi Chris, OK, nothing of the above was the reason. In my case it's simply this:
/etc/X11/xorg.conf.d/20-intel.conf Section "Device" Identifier "Intel Graphics" Driver "intel" Option "TearFree" "true" EndSection I added it when the tearing scrolling through large webpages annoyed me. As soon as I added it, the problems quickly started. Selfmade problem.
