Most likely you are now using EXA (newer intel drivers default to it),
a new acceleration architecture which does no longer accelerate lines
or circles - so it will cause software fallbacks.
You still can use XAA with the intel driver:
> Section "Device"
> Identifier "Videocard0"
> Driver "intel"
> Option "AccelMethod" "XAA"
> Option "XAANoOffscreenPixmaps" "true"
however its not certain how long this will work, there are already
reports that it crashes when using opengl apps.
