(Get the code!)
After the recent mesa update kwin composite in kubuntu is broken. Loging in from kdm works, the desktop starts, but when opening any aplication window (for example system settings) Xorg crashes and I'm back at kdm login. From this point also changing to terminal ctrl+alt+f1 doesn't work as by doing that I'm left with kdm bitmap and some graphical garbage is produced at the top of the screen.
When compositing is disabled everything is ok, also strangely when booting up the kernel with radeon.modset=1 and using KMS compositing in kde works as it should and the bug is gone.
My xorg.conf is unmodified default one so I'm not attaching it. The card is radeon x1200 (rs690) on a toshiba a215-7416 laptop.
