I upgraded to the 4.2 version from the 3.3.6. Previously, I used the 3.3.6 SVGA server, and ran X in with the resolution set to 1280x1024. Now, after upgrading, when I try to run X with the 1280x1024, my screen shakes and wiggles, especially when I try to resize any windows. Any ideas as to what to do? I'm using a KDS monitor + a 3dfx voodoo banshee card.
