Description: After today's update I ended up with broken KDE effects. It seems the desktop lost its acceleration. If I hit Shit-Crtl-F12, the KDE effects are switched off and the system works fine (like it did before). When I switch the KDE effects on, everything slows down terribly and it is impossible to work with the system. Disabling KDE effects helps again.
This problem only appears if I use OpenGL for rendering. Xrender works fine.


Additional info:
* package version(s)
* config and/or log files etc.


Steps to reproduce:

Switch on KDE effects in KDE, using the OpenGL background.
This task depends upon

pacman -Q consolekit

I'm having the exact same problem. My CPU jumps to 100% when desktop effects are on in opengl mode (xrender is fine). Even clicking on kickoff completely stalls the machine.

As a test I created a fresh arch install. I installed nvidia, then kde. The problem still persists, even with a completely new install.

I currently have consolekit 0.4.6-2 installed.

Is it still an issue ?
