Scaling on Wayland confuses the fullscreen.

[evertvorster]

When playing on Wayland, and having the monitors fractionally scaled, the fullscreen option does not work anymore, as it tries to display at the native resolution rather than the scaled resolution.

I know this is way outside of the issues we are dealing with, but adding in this report to collect more issues of the same type in one place until we have a developer that can get our screen output code whipped into shape.

Thanks. We can't do this in 0.9.x; so 0.10.x at earliest
