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"
> EndSection

however its not certain how long this will work, there are already
reports that it crashes when using opengl apps.
