@juerg,
To clarify, you’re saying that when you stop using your PC and the screensaver comes on, when you return to the PC and log back into your system, you find that Brave has been minimized? Or am I misunderstanding the behavior here?

Absolutely correct understanding.

Looks to be not specific on Brave but rather on Windows since other Apps are also concerned. No glue why this happen though.
