I have a similar issue:
@Vlad See video...
When I quit Orion, this issue goes away. I'm not exactly sure what in Orion is causing it, but I believe it has something to do with the new Window and Profile features.
I did a bit more testing and found that this problem begins when you right-click on the toolbar and select "Customize Toolbar...". Even if no changes are made to the toolbar, after you exit the customize window and evoke Mission Control, this problem is observed.
Orion, OS version; hardware type:
Version 0.99.123-beta (WebKit 615.1.16.1) - though this was happening on the previous version as well
MacOS Ventura 13.2 (22D49)
MacBook Air M1
