Cover half the panel
Fedora 34 with maliit-keyboard in a built-from-source Plasma Wayland session at 200% global scale.
When the virtual keyboard appears, it overlaps half of my vertical left-side panel. See attached screenshot. I suspect that the goal is to avoid covering the panel, because when my panel is horizontal, it succeeds at avoiding covering it. However when my panel is vertical on either side of the screen, the virtual keyboard overlaps exactly half of it. Seems like some width calculation didn't take into account the scale factor or something.
Fixed by Arjen Hiemstra with https://invent.kde.org/plasma/kwin/-/commit/7e25e20097fe8d140f7408b76fbf374fe5f33690 in Plasma 5.24.3
Apparently right edge panels are still affected; see Bug 459000.
