I can verify the patch works. However there are some issues

1. I see my colors are off when I use compiz as my WM and try to rotate the
cube.

2.piglit samity tests fail with this error:
spec/!opengl 1.0/gl-1.0-readpixsanity/gl-1.0-readpixsanity: fail

3. games like alien-arean and supertuxkart crash my system when trying to load
the game.

4. I can play video in mpv using opengl but get the following error:
[vo/opengl] Could not create EGL context!
