I hate to dig up an old report, but I am also encountering a nearly identical issue using Natty and Gstreamer running the video with "gst- launch playbin uri=file:///path/to/file" produces the same or a similar rendering error in which the frame is torn.
This happens more often (or is more noticeable) on lower resolution video. I am getting this issue both with the nVidia proprietary drivers on a GTX460 and open sources drivers on an Intel Chipset (Core i3 era) when the graphics card is removed. ** Attachment added: "GStreamBug416368.png" https://bugs.launchpad.net/ubuntu/+source/totem/+bug/416368/+attachment/2443685/+files/GStreamBug416368.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/416368 Title: Horizontal lines during playback To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/totem/+bug/416368/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
