That bar is the contrast region not being updated. >This issue occurs on Wayland. >On X11 we can see a glitch after the steps below. forgive me being stupid, but are you saying this is happening on X or wayland?
The bug shown in "after click on the next day" screenshot occurs on Wayland.
This is probably somehow my fault (I rewrote the layout of this applet recently). I don't see it on X11 FWIW.
Plasma 5.20 beta has a different calendar and this report is no longer relevant.
