I do not think it's a bug with KDE software. I can reproduce on Arch Linux running Wayland session of Gnome.

It'd be interesting to know which part of the software stack is responsible to render the cursor (in an XWayland app)?

The client tells X what cursor it wants and if it should hide
XWayland then provides a cursor to the wayland server 
the compositor renders the cusor provided by the client (which in this case is xwayland)

First step is to confirm if it truly is a kwin problem

Thanks David and Patrick. Also happens under kWin X11 5.25.3 and under Sway 1.7.4; will report it upstream.
