Popups stuck in Taskbar

Hi, since recently popups - like asking for pw etc, no longer pop up into the foreground above other apps like they used to do, but seem to stay stuck in the taskbar, so i need to click on them to open / pop up.

I said “seem to be stuck” beccause i realized that for instance when i close a Dolphin window, the pop-up was hidden behind it. So is this something that Dolphin causes?

I tried different conmbinations of the “Keep above / below others” settings, but wasn’t able to solve the issue so far. Any ideas?

My settings for Windows Behavior - Focus Stealing Prevention were the cause.

I had set them to “Medium”, and reverting to “Low” solved the issue.
