That's interesting.

A downgrade of xorg-x11* worked for me WITHOUT a downgrade of mesa*.

fglrxinfo and fgl_glxgears work fine for me.

[root ~]# fglrxinfo
display: :0.0  screen: 0
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: ATI Radeon HD 4800 Series       
OpenGL version string: 3.3.11631 Compatibility Profile Context

How would I know that upgrading mesa* had caused a problem? For example,
glxinfo, glxgears (which depend on libGLU.so.1) work fine.

The update upgraded the following mesa packages...

mesa-dri-drivers     x86_64  7.11-5.el6  ->  9.0-0.7.el6
mesa-libGL           x86_64  7.11-5.el6  ->  9.0-0.7.el6
mesa-libGL-devel     x86_64  7.11-5.el6  ->  9.0-0.7.el6
mesa-libGLU          x86_64  7.11-5.el6  ->  9.0-0.7.el6
mesa-libGLU-devel    x86_64  7.11-5.el6  ->  9.0-0.7.el6
mesa-libOSMesa       x86_64  7.11-5.el6  ->  9.0-0.7.el6
mesa-libOSMesa-devel x86_64  7.11-5.el6  ->  9.0-0.7.el6

...easy enough to downgrade now that I know how but do I need to?

Thanks,
