Well I don't know how often I told people to not animate opacity... In that
point qml sucks. It's way too easy to do inefficient things like animating
opacity or geometry.

Severe flickering and artifacts after re-enabling compositing *are* still an
issue with Qt 5.12.2

OSD stutter issue was fixed with:

Probably with Qt 5.12.0 it was a bug that was fixed by
https://phabricator.kde.org/R108:5d63b9c05bbe0c6545b3eeea98d95b40f800fb55

https://bugreports.qt.io/browse/QTBUG-73715 can be produced with modesetting,
and there was also https://bugreports.qt.io/browse/QTBUG-34492 on intel.

Another sure-shot way of triggering and observing the issues is to play a video
game (that suspends compositing I believe) and then exit it.

Hmm but I use Intel, these bugs started appearing from 5.12.0 (not 5.12.1) and
they happen both with the modesetting and the xf86-video-intel driver.

Another thing I should have mentioned in the steps to reproduce: the easiest
way to detect issues is to observe OSDs. They're meant to fade out smoothly,
but with Qt 5.12 the animation either fails entirely or stutters a lot.
