ADDITIONAL INFORMATION
Comment 1 DemonicSavage 2021-10-21 17:53:56 UTC
I guess I forgot the summary, which would be just

"There's a black bar centered in the panel, when a panel is transparent, and it shouldn't be there".

Comment 4 DemonicSavage 2021-10-23 00:01:12 UTC
I tried it in X11 and it doesn't happen.
Only on Wayland.
Comment 5 Michail Vourlakos 2021-10-23 10:48:56 UTC
This a KWin / NVidia / Wayland bug but I can not find its id in order to flag it properly as a Duplicate.
Comment 6 DemonicSavage 2021-10-23 13:18:45 UTC
I should have specified, bud I'm not on NVidia.
I have an AMD RX 6700 XT.
