I've also noticed the shaking resolutions problem. The problem seems to occur
with 640x480 and 800x600 resolutions. I've tried with both the trunk and the
tdfx-2-1-branch. 1024x768 seems to work well with both versions.

My setup:

    Voodoo5 5500 AGP
    Linux kernel 2.3.99-pre9
    Athlon 700
    MSI K7T Pro
