AS OF TODAY MARCH 25, 2011, I have same problem on Maverick(10.10) 2.6.35-28-generic Pentium III (coppermine)
Having same issue as described above (a shadowed portion left by context menu appearing above other windows, but falls behind flash objects) Also pieces of other context menus get trapped in it. Can sometimes get it to clear by duplicating the same context menu at same point on screen. Which tells me it does not always do it. How do I make it go away without logging out; what process do I kill? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/647127 Title: Persistent compositing glitches -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
