I've seen this issue on a Lenovo G550 32bit Core 2 Duo with integrated Intel chipset since 11.10. The problem survived an upgrade to 12.04. I've attached another screen capture. I typically encounter the problem after the machine has been asleep for any length of time.
I can confirm the 'compiz --replace' workaround which is the first progress I've had with the issue. I'll also note that bug #975306, while seemingly a duplicate, does seem to result in subtly different screen artefacts. 00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 07) 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) 00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) ** Attachment added: "garbled_unity_desktop.png" https://bugs.launchpad.net/ubuntu/+source/unity/+bug/985539/+attachment/3218009/+files/garbled_unity_desktop.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/985539 Title: Awkward graphic glitches (texture corruption) in Unity/Nux when opening lot of applications (intel video card) To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/985539/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
