Desktop effects + intel problem

after a lot of research i have concluded that kwin should try indirect
rendenring when it cannot use GLX_EXT_texture_from_pixmap, like compiz
automatically does (fusion-icon output):
* Detected Session: kde
 * Searching for installed applications...
 * Intel detected, exporting: INTEL_BATCH=1
 * No GLX_EXT_texture_from_pixmap with direct rendering context
 ... present with indirect rendering, exporting: LIBGL_ALWAYS_INDIRECT=1
 * Using the GTK Interface
 * Starting Compiz
 ... executing: compiz --replace --sm-disable --ignore-desktop-hints ccp
--indirect-rendering

I don't know why disabling "Direct rendering" option on kwin's desktop
effects config. dialog doesn't help. Also changing from other options than
"Texture from pixmap" doesn't help.

Maybe the problem has something to do with the opengl interface, as
GLX_EXT_texture_from_pixmap appears on my glxinfo:

:0.0
display: :0  screen:
0
direct rendering:
Yes
