I might have been a bit incorrect here, since I didn't have any
applications running at that moment, when I first ran into this problem.
I just started from scratch again ... deleted the plasma* files in my
home directory, rebooted and this time took care and chose the
plasma-desktop session and not the protected one (when I say protected
... I can't think of another word for "abgesichert" which is also used
when a windows crashes and gives one the choice of starting windows and
starting a protected windows ... I think you get the idea).
Started with setting up the desktop and tried to activate desktop
effects via schift-alt-f12 and bamm! Everything upside down again, the
screen flipped again, as I could tell from the control bar on the left
side of the screen and the open system-settings window. Funny "side
effect" .. while visually flipped I still had to click in the areas,
where all the buttons are supposed to be (hope you understand what I am
talking about ... :-) )
Since you mentioned OpenGL I chchanged the composite type to Xrender and
I don't the problem there (means I can activate effects without the
flipping of the screen).

Nope. I was talking about checking "enable desktop effects at startup".
I have it disabled for now.

Nope ... no problem with the widgets and in fact I have never seen this
defaulted behaviour. On my end KDE starts with the last state (means
"locked" when previously locked and "unlocked, whern previously unlocked).
