[Bug 886496] Re: KDE Screenlock renders machine unusable since software-upgrade of Nov. 4th, 2011

I have this bug after upgrade to kubuntu 13.04.
After unlock both notebook's and attached monitor screens remain black (with some artifacts) and X-server eats CPU. After a minute or two it may eventually unlock the screen. On "ps" via ssh it looks like this:

dosya     2578   0.0  0.1 515792 21600 ?        Sl   15:34     0:01  \_ kdeinit4: ksmserver [kdeinit]
dosya     2585   3.2  0.7 943424 94536 ?        Sl   15:34  11:35  |   \_ kwin -session 10d4.....
dosya    20107 0.4  0.0               0           0 ?        Z     21:22    0:01  |   \_ [kscreenlocker_g] <defunct>

It is not 100% reproducible, though I noticed some correlation between running chromium and this bug. I suppose kscreenlocker hangs when some OpenGL-enabled application is running.

 I tried different fglrx versions but it didn't help.
