It looks like a race condition during boot. If it happens the visual effect can even be seen, while booting, before the login screen. The login screen is always ok, but afterwards the effect reappears.
There is another video effect which is new compared to Karmic. In the boot sequence the screen has sometimes just a noisy picture and than the old or a new picture reappears again. (while changing video modes?) -- VGA screen sometimes is croped and has dithering DVI Screen is always normal ATI x800 https://bugs.launchpad.net/bugs/579028 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
