SUMMARY The grouping plasmoid animations work incorrectly when adding new widgets inside. Here's a demonstrative video - https://youtu.be/JHhhv3Bv7-E. You can see how the first animation for the white line is okay, but as I keep adding new ones, the animation goes out of bounds for new widgets. It should work with any widget. STEPS TO REPRODUCE 1. Add a new grouping plasmoid 2. Add a widget inside of it 3. The following widgets added will have an incorrect animation SOFTWARE/OS VERSIONS KDE Plasma Version: 5.15.5 KDE Frameworks Version: 5.58.0 Qt Version: 5.12.3
There is also an animation bug when removing the widgets inside the grouping plasmoid. You can see in the video how the white line moves vertically when it shouldn't.
This appears to be working as expected in current git master.
