    Description

      Running a QML Animat_or_ in a Wayland client is very choppy and averages out at about 15 FPS.

      See the attached examples: the first uses a RotationAnimation and the other a RotationAnimator.

      The first gets a steady 60 FPS on Wayland, pure-qml and QtAM. The second runs very choppy in all the compositors (the 15 fps number comes from the QtAM frame-timer example).

      The exacty same thing happens on all our platforms: desktop NVIDIA, Radeon and Intel, as well as on a NUC.

      Both the examples run fine at 60 FPS on X11 though. The also run fine against 5.12.
