Ventura: Using Stage Manager windows are often resized after sleep …

[MacUelef]

I upgraded to macOS Ventura a few days ago. But no I am using Stage Manager (besides Spaces) I got a problem that is annoying: After waking up from sleep some of my windows (e. g. in Safari) are resized. Using the whole screen length form from the top to bottom for a window after sleep the windows only use about 60 % of the height and are positioned at the buttom of my screen. Deactivating Stage Manager everything is ok again.
Does anyone have any suggestions what I can do to prevent resizing the windows? The strange thing is that not all windows are affected.
(My setup: Mac Studio, Apple Studio Display)

Ok, I switched back to Spaces – Stage Manager seems to have some bugs regarding window sizes and the problem is that arranging apps cannot be stored. In Spaces I can assign apps to different spaces – they will still be there after restarting my Mac.
Stage Manager is a nice looking feature but it's not well thought out (like the new settings app that I really don't like).
