F16: Sandy Bridge -> lags, missing effects, ui-crashes

[Reindl Harald]

Hi

i notice growing problems on F16 with "Intel Sandy Bridge" graphics

* desktop effects in KDE partly not working (3D cube as example)
  this worked well over months after upgrade from F14 to F15 and

* sometimes the whole desktop hangs with display errors
  like missing parts of windows solveable mostly by logout
  but sometimes resulting in a complete system hang

* lags while starting applications or activate windows
  of running apps

may it be that this is caused by major kernel updates
without update the graphics stack?

my hardware should normally not show any lags because
a Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz with 16 GB
RAM was a short time ago a real high-end machine
