I have this issue with nvidia hardware and the nvidia driver since 8.04 Always only while using compiz. But since compiz is now also unitys problem, it's fair to say it's also an important one finally.
Tried severall workaround and some bring good performance but aspecially videos will always tear a little bit with compiz and since alpha 2 from natty also unde unity - of course. nvidia gforce 8400gs and latest nvidia pentium 4 link to german ubuntuusers thread about this issue http://forum.ubuntuusers.de/topic/tearing-bzw.-streifen-in-videos- nvidia/3/ Hopefully some highly skilled and canonical programmers build from pure fire and stars will smack the s$%§ out of this bug ... pls -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/600178 Title: Screen tearing when dragging window, in videos and other large screen redraws (on nVidia GPU) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
