Plasma 6 Wayland window geometry issue

[hecate]

(context: two monitors; 3840x2160 on the left, and 3440x1440 primary on the right)

occasionally, upon starting the game, the 'native resolution' window will be a bit too tall for my monitor.

changing the resolution radio button to custom and then hitting apply (default 3440x1440) fixes this, but then the game stops responding and needs to be relaunched. It's always fine after that relaunch.

forgot the screenshot: the window itself is the correct geometry, but the render itself is shifted up by like, I dunno, 20 or 40 pixels.
