WalletWasabi: macOS and Ubuntu split screen doesn't work properly and freezes

General Description

Split-screen freezes, isn’t by default occupying exactly half of the screen, can’t be adjusted when trying to split screen a larger window (more than half the size of the screen) versus other apps (macOS and Ubuntu).

Please refer to point 2 here: https://github.com/zkSNACKs/WalletWasabi/issues/3782#issuecomment-659103129

How To Reproduce?

1. Expand the window size to occupy more than half of the screen.
2. Hold down the green expand button on the top left-hand corner of the window and select ‘Tile window to left of screen’.
3. Notice how the screen just freezes and cannot be resized to only cover half the screen.
