Think I'm seeing this same behavior from time to time, on an -ati system. In fact I reported it upstream as a driver bug before finding this report:
https://bugs.freedesktop.org/show_bug.cgi?id=36699 So like the commenter above I think it's not a problem specific to -intel. Think this is the same as bug #708749 which is -nvidia. That user also found that killing metacity made the regions go away. So I think it's not an X issue at all, but I'll leave it open against xorg- server until it's more definitively understood. ** Bug watch added: freedesktop.org Bugzilla #36699 http://bugs.freedesktop.org/show_bug.cgi?id=36699 ** Package changed: xserver-xorg-video-intel (Ubuntu) => xorg-server (Ubuntu) ** Changed in: xorg-server (Ubuntu) Importance: Undecided => Medium ** Changed in: xorg-server (Ubuntu) Status: Incomplete => Triaged ** Changed in: metacity (Ubuntu) Importance: Undecided => High ** Also affects: xorg-server via http://bugs.freedesktop.org/show_bug.cgi?id=36699 Importance: Unknown Status: Unknown ** Summary changed: - [i965gm] compositor produces artefacts starting in maverick + compositor produces artefacts starting in maverick -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/654768 Title: compositor produces artefacts starting in maverick -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
