Kubuntu: windows placed outside screen

[floooh]

...on my new Asus Zenbook with KDE Plasma 6 Wayland session (2880x1800 display and 200% scaling) windows are placed outside the visible screen area.

Hmm ok, that's because for some reason there's an 'Unknown' display in the KDE display setting configured next to the builtin display, and sokol_app.h seems to place the window on that 'Unknown' display.

Disabling that 'ghost display' fixes the problem, but WTAF.

...yeah, the screen-size is reported as the combined monitors by xlib, but I don't seem to be able to detect that situation because the number of screens is reported as 1. Googling around this seems to be a somewhat common issue in Ubuntu 24.x
