I enabled vsync with Catalyst Control Center and running 'aticonfig --initial --input=/etc/X11/xorg.conf --overlay-type=Xv', but the video still tears. I tried several Xorg.conf settings but without any improvement. Removing Xorg.conf does not change anything. I have this problem since Hardy with a Radeon HD 3650. Even Windows XP with Catalyst driver tears. Some time ago I switched to a Radeon HD 4670 (see lspci-vvnn.log), but even this card tears. The videos tear and do not flicker. This bug also occurs with Compiz disabled.
