Priority: P2: Important
Affects Version/s: 5.15.5
Fix Version/s: None
Environment:I've checked it on Linux but I also have the confirmation this happens on Windows with a different hardware configuration.
Sometimes graphical effects draws incorrectly after changing window visibility.
Here's minimal reproducible example:
This has to be viewed with Material style, for example when using with qmlscene one has to pass
(and ignore the warning).
Steps to reproduce: click to the visible window several times (usually <20)
I haven't found any workaround for this - requesting update after the window gets visible doesn't help. When you have more than one popup, it always makes a glitches all or none at the time.
