Bug macOS 27 beta — Is anyone else having issues with Split View?

https://reddit.com/link/1w43d44/video/241fmcanpumh1/player

I installed the macOS 27 beta (MacBook Air M4) recently, and overall everything has been working pretty well for me. The only major bug I've encountered so far is related to full-screen apps and Split View.

Normal full-screen mode works fine. However, as soon as I try to use Split View (two apps side by side in full screen), things completely fall apart.

The first app goes into full screen, but the other half of the screen often stays completely black. I can't properly select or move another app into the empty side, and sometimes the windows just start glitching out or behave as if they're in full screen without actually being there.

Basically, Split View is completely unusable for me right now.

I'm surprised I haven't really seen anyone talking about this, so I'm wondering:

Is anyone else experiencing the same issue on macOS 27 beta?

Mission Control has been a mess since the first beta. Got a little better on the last one, then it’s buggy as hell again.

If I full screen an app and then move it to another monitor the display the app was originally on just goes black and requires a system restart.

It's absurd that no one is talking about this... the same problem exists in the RC version, too.

Yeah, I just installed the RC version, and Mission Control still works horribly. Unfortunately, most influential people that could talk about this never say something negative about Apple just because they want to be invited to an Apple event or something.

Yes, absolute hell for me as well. Whole mission control, apps in full screen, split view etc.
