I used Metacity compositor in previous versions, and the problems only started to occur with Maverick.
This affects AMD64 as well, with the final release of Maverick. The problem occurs in two situations which I can find: 1) When a menu (context or otherwise) is exited, the menu sometimes is not hidden. 2) When an image or selection is dragged in Chromium browser. Presumably, this uses the same mechanism to show the selection being dragged as other applications use to show menus. Once the menu is no longer supposed to be on the screen (I.E. it has been exited, but garbage still remains visible), interaction with the garbage goes to the window behind it. Applications such as X Window Information are unable to detect the garbage. ** Tags added: amd64 -- 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
