Since a couple of days OpenGL composition method stopped working. When I try
to switch to it it displays this (pretty useless) message.
Failed to activate desktop effects using the given configuration options.
Settings will be reverted to their previous values.
Check your X configuration. You may also consider changing advanced
options, especially changing the compositing type.
And it reverts back to Xrender, that works fine, but is really slow.
The xsession-errors says something, but I can't undertand it:

I'm using gentoo ~amd64 10.0 no-multilib profile, kwin 4.4.1, xorg-server
1.7.6 and I tried all the available versions of the intel drivers, including
9999.
I cannot remember of any recent upgrades that might be related to the problem,
but. as this is ~arch there are upgrades everyday, while it might take a week
before I log out of my kde session. So I'm not sure of what upgrades may have
iterfered.
I tried with a brand new ~/.kde4, but that didn't help.
I'm running out of ideas, please help me :)
