Comment 1 for bug 137388

Same here, except that usually LIBGL_ALWAYS_INDIRECT desapears after logging out and in again (once or twice ...)

The variable is set in /usr/bin/compiz when glxinfo does not report GLX_EXT_texture_from_pixmap twice. Weird thing is, openning a shell, unsetting the ALWAYS_INDIRECT thing and running the same test, it works .... texture from pixmap is reported twice as expected ...

I'll comment out this check and see what happens on the long run.
