With  an old Intel GM45 Express chip, there are no regressions after 
applying the patches and rebuilding Mesa.

Nevertheless I see the same behaviour and libGL errors as Kevin with 
glxgears and eglgears_x11.

I think setting layers.acceleration.force-enabled in Firefox in this 
older chip will never work (videos still get a magenta hue).

mpv work as before, but there is no VAAPI/VDPAU (I don’t know if it is 
even possible, I have not tested further).

Summary: the Mesa update does not break functionality.

Thanks for your work!
