opengl problem with kde 4.10.1

[FrancoisVal]

Hello everybody,

Since I updated to kde 4.10, opengl is not more detected by Kwin and therefore I can't use the desktop effects. After some search, I found that post of the kde forum: http://forum.kde.org/viewtopic.php?f=111&t=109963
If I set the environment variable KWIN_COMPOSE like explained there, these effects become available again but then , KWin use more than 100% of the CPU.

Can somebody explains what's happening ? I have an Intel HD Graphic card using the i915 driver
Thanks in advance for your help.
