I am running Hardy amd64 with a XFX PVT73EUAQG GeForce 7300GT 256MB 64-bit GDDR2 PCI Express x16 video card and restricted drivers. At my monitor's native 2560x1600 resolution, 3D effects (viewing the Desktop Wall or switching desktops in Compiz, or using any screensaver with or without Compiz) cause a horrible flickering. This doesn't happen at any other resolution. How can I diagnose and fix the problem?
