I can confirm this with latest Hardy. I have enabled vblank for OpenGL and it works fine, compiz runs with 60 fps and everything looks great but all XV video players have a tearing and choppy output. It seems that XV Syn to vblank doesn't work with compiz. It works fine if I disable compiz or use gl output instead.
VGA compatible controller: nVidia Corporation GeForce 8800 GTS 512 (rev a2) nvidia-glx-new: Installiert:169.12+2.6.24.10-11.29 Mögliche Pakete:169.12+2.6.24.10-11.29 It could be easily tested with mplayer benchmark. If vblank is enabled for OpenGL the video with gl2 output runs smoothly and at normal speed but the one with XV runs very fast since there is no sync. mplayer -benchmark -nosound -frames 1234 -vo gl2 VIDEOFILE mplayer -benchmark -nosound -frames 1234 -vo xv VIDEOFILE More information to the problem: http://www.nvnews.net/vbulletin/showthread.php?t=85301 ** Changed in: linux-restricted-modules-2.6.24 (Ubuntu) Status: New => Confirmed -- compiz+nvidia: tearing in xvideo (totem/mplayer/VLC) https://bugs.launchpad.net/bugs/151674 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
