Comment # 19 on bug 62889 from Alexander von Gluck

I can confirm that after disabling ColorTiling that Steam loads properly.

So it looks like:

 1) The ColorTiling bug moved from Gnome 3 back to Steam after updating Mesa /
libdrm
 2) The Patch makes no real difference.
 3) Disabling ColoringTiling makes Steam function.

So it looks like things are finally working at this point.

Going to play some random Steam games to see if there is any corruption or CP
stalls as with the HD 5870
