Split screen has stopped working. I’ve checked ‘Displays have separate spaces’ and logged out/in and even restarted several times. Might be since upgrading to Ventura but can’t be certain. Any ideas?
Solved. Updating to OS 13.2 did it.

Bumping an old thread, because I just started encountering this issue today.
If I try to put Things and Fantastical into split screen with each other, I get a result that looks like the screenshot on this page (just different apps).
The odd thing is, it was working yesterday with no problems. I tried restarting. No dice. Yes, I checked the “Displays have separate spaces” setting, and it’s fine. I was on macOS 13.2 this morning, when it wasn’t working — as I was yesterday, when it was working.
I updated to 13.3, hoping it would fix things. Nope.
I’m at a total loss here. Any ideas?
Edited to add: the really weird thing is that both applications will happily go into split screen with Safari. They just won’t go into split screen with each other.
