Public bug reported:

Binary package hint: kdebase-workspace

Hardware & Software Specs:
   Kubuntu 9.04 (updated as of 2009.02.12)
   Lenovo S400 laptop with Intel Core 2 Duo, 4 GB RAM, ICH9 family chipset
   Intel 4-series mobile graphics chipset (rev. 07)
   160GB Mobile HDD
   Graphics Drivers: Using Kubuntu supplied Intel graphics 2.6.1 series, UXA acceleration enabled
    3D compositing enabled under KDE with direct rendering & VSync turned on.  Texture from pixmap and "Nearest" 
texture quality in use.  Functionality checks disabled.

   Using Intel's UXA acceleration setup, after resuming from suspend to ram, some (but not all) kwin desktop effects
will begin to cause failures and kwin must be restarted to correct the problem.
   Desktop effects that use the "full screen" like the  "Desktop Grid" or "Present Windows" effects will fail to start, but then after several seconds will immediately start running continuously (as if the user was constantly turning the effect on and off at very high speed).  The only solution is to kill kwin and let kwin restart.    Other desktop effects like having a transparent window do not seem to fail in the same way however.
