shadow: Maximizing a 1920x1200 on a 1920x1080 display creates "weird artifacts"

[stdedos]

Describe the bug

I understand the window doesn't fit vertically. But it looks downright ugly for no reason (it's not that "somehow" it fits looking like this)

Trying to click with the mouse, or selecting text fixes this

but scrolling breaks it again

[totaam]

Can you please include some server -d compress log events from the problematic updates? (and xpra info)

My guess is that some of these screen updates are scaled and some are not. The window should be using a fixed size, even if that means not fitting on screen, so there should be no scaling involved.

It seems to not be replicating
