Patch to fix the redraw problem

Description of problem:
Running QT or GTK apps results in fonts, icons and other details either failing to draw or rendering with incorrect colours. Running Xdmx with -norender fixes the problem, but it is very slow and an unacceptable solution.

How reproducible: Every time

Steps to Reproduce:
1. Start xinit on client nodes
2. startx `which gnome-session` -- Xdmx :1 -display host1:0 -display host2:0 +xinerama
3. Many aspects of the windows fail to render.  Firefox has problems too. Happens with KDE and the same apps run under twm.
Additional info:
I have included a patch which can be applied to the SRPM and fixes the problem.

The patch isn't correct, but I'm pretty sure the equivalent problem is still present in RHEL7.
Comment 4 Adam Jackson 2014-06-12 13:22:55 EDT
After some digging, it looks like this is the same issue as:


Which was fixed upstream in the xserver 1.2 branch.  Therefore I believe this issue is resolved in all RHEL6 and RHEL7 X servers.
