--- Comment #32 from David Edmundson <kde at davidedmundson.co.uk> ---
Can you download the above and run "qmlscene test.qml"

It's a timer, a double click, and an animation.

I'm somewhat confused how there could be a link, and debugging with a whole
plasma is an uphill battle as it has too much noise.


Qt's Timer driven from the frame rate. QAnimationDriver is, but they serve
different purposes.

We have seen issues with QAnimationDriver getting confused.
Running "kcmshell5 qtquicksettings" and selecting the basic render loop can
suppress that
