<pre>I checked the Xorg logs from the latest Fedora Rawhide and up-to-date Fedora 21
and it's possible that it all comes down to Color Tiling. Whereas xorg-server
1.17 reports Color Tiling as enabled it's disabled in 1.16. Is this supposed to
happen? Is there any way I can force Color Tiling in 1.16 (Option "ColorTiling"
"on" doesn't help)?</pre>
