Description Noah Davis 2020-12-03 16:12:08 UTC

SUMMARY
This might sound like expected behavior, but Plasma now has hover effects enabled by default via the useHoverEffects QStyleHint in plasma-integration. QQC2 automatically enables hover effects when this style hint is enabled.

STEPS TO REPRODUCE
1. run `QT_QUICK_CONTROLS_STYLE=Fusion kirigami2gallery` (any style that doesn't explicitly set hoverEnabled will have the same issue)
2. Go to the Button gallery page
3. Hover over all of the buttons

OBSERVED RESULT
None of the buttons show the hover effects they would normally have.

EXPECTED RESULT
Buttons should have hover effects if Qt.styleHints.useHoverEffects is true.

Potential Fix

This would be the obvious fix. However, I am not sure what side effects this might have. At first glance it seems to fix the problem.
