The attached swap-buffer-composite-test.c demonstrate that
glXSwapBuffers tears the first line of the screen.
I have tested at 1920x1200 at 60Hz and 1024x768 at 60Hz.
kernel 2.6.30
xserver 1.6.1
xf86-video-intel from git
b5cd2130f97591f4a387db1b98c940c30bc6404c with
our patches posted to this list
for portrait mode and 2048x2048 XV.
Mesa from git, branch origin/mesa_7_5_branch, commit
8f382fd3f396e182255fe084bc32648b98ca1d94
I assume that this is because the GPU has not been
programmed correctly.
Do you want this logged in bugzilla?
