Do you mean GL performance degrades? That's probably not directly related to
EXA.


Does this patch help for the problem reported originally? It implements a
simple defragmentation algorithm.

Whether it helps or not, please provide the output of

grep Defrag /var/log/Xorg.0.log

after running for a while with the patch applied. I'm still looking for better
heuristics for when to do the defragmentation.

Note that there have been some recent EXA changes only available on the xserver
master branch so far which could help for this as well (or should at least
improve text performance a lot).
