add the following line to device section:

The Device section of your xorg.conf should look to something like that :
Section "Device"
Identifier "Videocard0"
Driver "openchrome"
Option "AccelMethod" "EXA"
EndSection

if it still doesn't work, try with :
Section "Device"
Identifier "Videocard0"
Driver "openchrome"
Option "NoAccel"
EndSection

Adding the following line to the Device section of the xorg.conf fix the
issue:

Option "AccelMethod" "EXA"

Option "AccelMethod" "EXA"
Option "ExaNoComposite" "True"
Option "MigrationHeuristic" "greedy"
Option "ExaScratchSize" "8192"
Option "MaxDRIMem" "16384"

I believe some non-EXA problems are avoided with;
Option "SWCursor" "true"
Option "NoXVDMA" "true"

From some tests I also have still active this;
Section "Extensions"
Option "Composite" "enable"
EndSection
