AIGLX - fullscreen off-center

I'm getting wierd behavior when running 3d games over AIGLX, and the
only difference that I see is in the authentication, which seems
My setup is an application node hosts the game and sends rendering data
to the display node. I can send my xorg.conf, but I doubt that's
helpful right now. My driver on the display node is the i915 intel
- using ssh/X forwarding, everything is fine.
- when I authenticate using xauth, the fullscreen is off-center. if I
then try X forwarding through ssh, the screen is centered correctly
through the ssh forwarded socket and, when I logout of the ssh connect,
the X forwarding over xauth is also centered correctly. wierdo....
The symptoms are the same for Tremulous, but this time instead of being
off-center, the screen is simply not full-screen (it's about 2/3 of the
full-screen). If I do the ssh-thing, then this also "fixes" the full
screen for the xauth authenticated forwarding. The only other info I
can think of to post is the xrandr info:
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 1280 x 1280
VGA disconnected (normal left inverted right)
LVDS connected 1024x768+0+0 (normal left inverted right) 286mm x 178mm
1280x800 59.9 + 60.0
which is the same for both "non-centered" and "centered" sessions.
Can somebody point me in the right direction to look? I don't mind
looking into mesa/ intel driver code.
