Driver bug. I could assume that the screen layout (or resolution) changes on login.

Does this happen on *every* login?
Please attach the output of "qdbus org.kde.KWin /KWin supportInformation" (call when KWin is running and compositing not suspended)

Compositing
===========

Compositing is not active

Transparencies always disabled when in login

> call when KWin is running and compositing not suspended
As long as compositing isn't active, the backtrace is close to worthless :-(

If you cannot activate compositing at all (SHIFT+Alt+F12), please provide the output of "glxinfo" instead (to hint the GPU)

Also: what's the output of
   grep -i glamor /var/log/Xorg.0.log

 Thomas Lübking, thanks for your help. With (Shift + Alt + F12 ) desktop transparencies returned to work.

Sorry for my poor English.

Don't worry about your english, but please dump
    qdbus org.kde.KWin /KWin supportInformation
when the compositor is active ;-)

"qdbus org.kde.KWin /KWin supportInformation" after execute  (Shift + Alt + F12 )

> Qt Graphics System: native
Wild guess: set this to raster in "kcmshell4 kwincompositing" (3rd tab, kwin will restart)
The aurorae decoration doesn't like the native graphicssystem and w/ glamor acceleration, I could assume a 1-process, 2-contexts "conflict".

But it's really just a very wild guess.
