When I tried Mesa 7.8 from Debian experimental I got stuttering 3D
output, at least in neverball and glxgears. I tried libdrm2 2.4.18,
2.4.21, kernel 2.6.34, 2.6.35-rc5, and the Intel driver 2.11 and 2.12,
without a change to the stuttering. The Xserver is 1.7.7. the FPS
output in glxgears was even higher than with Mesa 7.7, but it looked
ugly because of the stuttering. Do you have a chance to downgrade to
Mesa 7.7?
