KDE 6 Window Overlays

I’m running KDE Plasma 6.3.3 and KDE Framework 6.12 0 with QT framework 6.8.2 on Fedora 40. On most applications when I use an option from navigation menu such as help>about the application overlays the entire window with the help>about screen. Previously it would just pop up a window with the requested information. My question is is there a way to return to the pop up window instead of an overlay? This happen in Konsole, Dolphin, evolution, gramps, and a host of other applications. Really annoying!

Thanks in advance for any help or suggestions. In case this isn’t an appropriate platform for this question please redirect me to another more appropriate platform.

I do not see this behaviour.
I did wonder if kde was remembering the maximise, but that is not remembered.

Is this going full-screen or maximised (leaving the task bar visible)?

It is not maximise but just covering the original window whatever size it was. The problem I see is the X for closing the window is exactly of the X of the original window and if the system reads 2 mouse clicks it closes both the original window and the pop up.

Not only the above mention problem, sometime I just need to transcribe some info from the pop up into original window and it was nice to be able to see both pop up and original.

Can you share a screen shot showing this?
