Description Martin Koller 2021-06-04 10:13:52 UTC 
Right click on the TitleBar -> More Actions -> Configure Special Window Settings
-> "Add property"
A strange looking list is embedded. When I now use the mouse to press-hold-drag the right scrollbar, the content of this list weirdly jumps a few pixels up then a few pixels down while moving the mouse

I can confirm this bug since the "refactoring" of the effects window.
Could we at least go back to the previous -working- classic window list, while thie bug is addressed, please?

Thank you for the video.
Can you confirm if this happens with the breeze widget style?

Yes, unfortunately, it does.

Managed to reproduce. 

Notes: 
 - scrolling with trackpad is fine
 - it's most apparent when moving the scrollbar handle slowly
 - this does not happen in the system settings sidebar which should be similar

Cause is the onContentYChanged on the inner scrollview in Kirigami's Overlaysheet which is why it only affects this. 

Adding an early return "fixes" this. Though I assume it's there for some reason.

Raising priority due to number of duplicates and visibility to users. It's a very annoying issue which will only become more annoying as we continue to use more scrollable OverlaySheets.

Maybe for scrollable OverlaySheets, we could give up on the whole "anchored to the bottom" thing and just make it a dialog.

Or maybe scrollable OverlaySheets are a mistake in general and we should use a different UI element when the contents need to scroll.

OverlaySheet has been refactored to not do that jumpy animation ever. when it opens it won't change its position until is closed again
