Antialiased fonts makes scrolling noticably slower |

Hello,
I'm starting emacs 23.0.60, on gnu/linux
- under X
- with free ati graphic drivers (r350 IIRC)
- 1.7Ghz x86 cpu
- with option -fn "Dejavu Sans Mono-14"
In a long buffer, if I do
C-u 1 C-v
, then I do
C-x z (holding this z)
to scroll line after line.
Buffer scrolling is slow, letter drawing make them blink, and cpu
peaks at maximum.
Do everybody experience slowness with antialiased fonts ? Is that
inherant to the hard work required to compute antialising, or to a
poor performance in 2D on my box, or something else maybe ?
Of course I do not experience this behaviour at all when antialiasing
desactivated.
Thanks
Paul
