2 screens, C1 window is jumping after a middle centered dialogue is popping up

I've already reported this bug, but to no improvement so far:

C1 is spread over two screens in one window. Browser on left 5K screen, editor and tools on right 4K screen with adjusted resolution. Since version 23 and also some versions of 22 a bug came back:

Occasionally the app starts in the size for two screens on the secondary (right) monitor. No idea, why. So I need to pull it all the way to the left. I'm not working in "fullscreen" mode. I just expect C1 to behave like any other normal window which is not jumping around like a donkey.

If I edit an intelligent collection or create a new collection from a selection, the main window jumps to the left. It appears, the devs want this bloody pop-up-window to be in the middle of the main window and cannot handle the difference in native and adjusted resolution?

The last version of 22 didn't behave that awful and I don't know if it's Ventura or C1 23 doing a bad placement job here, but it sucks every time I need to pull the window back to it's original place. 16 versions and still this kindergarten-stuff?
