Created attachment 176863 [details] screenshot of the issue I attach a screenshot of the problem. The game is playable but it's a bit annoying that the background image ends up being misaligned. Oddly I cannot reproduce this on my desktop, even resizing the window. Perhaps it happens just at the beginning and on tablets there's never any resize so it remains like that.
This happens on all wayland sessions. Passing -platform xcb is a valid workaround. I'll patch the .desktop file on Debian to always launch using X11 to keep the game playable.
