I have this same bug and would like to provide this additional information to track down the problem:
-) It did not happen with Ubuntu 11.04 Natty -) It DOES happen with Ubuntu 11.10 Oneiric, even with the same jvm (oracle 1.6) -) It happens only if the Frame starts up in maximized mode, but not if the frame starts in non-maximized mode. -) If you toggle maximized state of the frame off, the offset problem will disappear. Toggling it back on will not make it appear again. -) To me it seems that the vertical offset is exactly the height of the global menu / window title bar. -) I currently have my Unity Launcher set to "hide never". This causes popup elements of a java application to be horizontally misplaced: They are shifted to the left by width(launcher) pixels. This horizontal misplacement also is fixed as soon as the maximized state of the frame is changed for the first time. So, there seems to be some window initialization issue here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/878934 Title: Menu selection is wrong in Java apps To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/878934/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
