Comment 75 for bug 303697

artik,

I really think a lot of the blame (at least half?) belongs with the xorg devs. Fglrx worked great for me on intrepid. It wasn't until they improved X that the incompatibility issues began.  I wouldn't be surprised if the devs are so excited by the prospect of finally being able to code their own drivers up to industry standards (since ati/amd opened their sources) that there just isn't as much interest in getting the proprietary drivers to work.

Status in AMD fglrx video driver: Confirmed
Status in “fglrx-installer” package in Ubuntu: Triaged

Bug description:
Videos tear when I play them with xv extension. 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.
