I see this warning, too. I have not noticed any problems resulting from it.

That might be a reason for the rendering latency, if your window manager

I would try to add
Option "AccelMethod" "UXA"
to this section and restart X. I also have a chipset from the 965 series
(965Q) and in my case switching to UXA (which enables DRI2) improved
