[SOLVED] kwin crash when using OpenGL mode after upgrading to 4.7

I have a Ideapad Y460 (Graphic: ATi Mobility Radeon 5650). Recent days I upgrade my KDE from 4.7RC (4.6.95) to 4.7 (4.7.00) and also Catalyst from 11.6 to 11.7.

Update:
The problem has been solved. I used [kde-unsupported] source and kdebase-workspace package in that source contains OpenGL ES support while Catalyst doesn't support it. Thank @csslayer.

But when I use OpenGL mode, kwin crashed. I run

kwin --replace

to start kwin, then the Desktop Effect shows:

OpenGL compositing (the default) has crashed KWin in the past.
This was most likely due to a driver bug.
If you think that you have meanwhile upgraded to a stable driver,
you can reset this protection but be aware that this might result in an immediate crash!
Alternatively, you might want to use the XRender backend instead. 

And there is a re-enable button. But the systemsettings window crashed when I pushed it.
I checked ~/.xsessiong-error and it shows this:

X Error: BadWindow (invalid Window parameter) 3
  Major opcode: 20 (X_GetProperty)
  Resource id:  0x1c0015a

I downgrade Catalyst but the problem still exists while KDE4.7 RC run well on my laptop. So I'm not sure whether it is caused by kwin or by Catalyst 11.7 or other packages.

Does anyone know the solution? Thanks for your patience.
