I'm also experiencing this issue frequently, at random, with Unity and classic GNOME, on two different computers running up-to-date copies of 11.04. (One's a desktop with an NVIDIA display adapter and a 1280x1024 screen; the other's a netbook with integrated Intel graphics and a 1024x800 screen.)
One additional thing I noticed is that pressing Alt-Tab usually makes the dead zones disappear for a while. (This workaround is the one thing keeping me from pulling my hair out...) Maybe it's related to the Compiz Alt-Tab plugin? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/709461 Title: Application windows can sometimes fail to display and will mask regions of the screen -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
