Bug in stage manager with two (or more) instances of an app

https://reddit.com/link/1hpiyq0/video/puxn1dc86y9e1/player On my Macbook M2 air, I have this bug since Sonoma, still not fixed. Restarting the OS doesn't help. Someone posted a very similar issue [here](https://www.reddit.com/r/MacOS/comments/1ai59yc/nasty_bug_in_stage_manager/). Has anyone else encountered this problem or found a solution?
