Confirmed.

3. Minimize main window on second monitor

Can also "roll down in the window". The window will move to another screen.
But if you expand the window in the usual way to full screen, without gluing it to the top of the screen, there is no such issue.

This is most likely a problem in Qt. Can someone test a qBittorrent build with a different version of Qt (6.8 or 6.9) while keeping all other conditions unchanged?

I ran into this issue today, but I think I have made it go away again - at least for now.

These were my steps
Restore the window - making it windowed instead of maximized.
Minimize the window and restore it.
Maximize the window.

After that, it would again restore to the correct monitor after being minimized.
