After I switched from modesetting to the intel driver (due to bug#111105), I
see a lot of video stuttering. That is, sometimes the video jumps back and
forth. Only when played fullscreen, it seems. mpv disables compositing in that
case, I think.

And not only the video. This firefox window on another screeen shows the same
symptom while I am typing -- letters dismiss and appear again.

Well it still can be bug#111105 after all -- showing an old buffer on the
screen under some circumstances.

mpv-0.29.1-28.9.x86_64
