Error of Beryl+AIGLX on i965

[Wang, Wei Z]

Pick up the thread :) I have tried FC6-32bit (compiz + AIGLX) on i965, seems everything works well (some of my pals got the same result on FC6-64bit + i965), except the following complaints:

libGL warning: 3D driver claims to not support visual 0x5a
compiz: No stencil buffer. Clipping of transformed windows is not going to be correct when screen is transformed.
compiz: water: GL_ARB_fragment_program is missing

Which may impact the _water_ effect, this issue is also mentioned by https://bugs.freedesktop.org/show_bug.cgi?id=9058


To my surprise, Andrew, the white screen issue doesn't appear, and "GLX version: 1.2" is reported by glxinfo. I am just wondering that if the "GLX_ext_texture_from_pixmap" issue is still there?



Thanks
- Wei
