Menu selection is wrong in Java apps

This bug is not reproducible in unity-2d which means it's actually a unity3d bug, furthermore it applies to all lists and comboboxes, not just menues.

I'm not able to reproduce this bug at all with java-7-openjdk. In my case the correct menu gets selected when I move my mouse over it. Could you check if you're running Ubuntu with the latest updates?

Even after that, this seems to be more of a Java bug to me rather than a compiz/unity bug

bug 755406 could be related.

I have 6 fully updated ubuntu oneiric pc's, and the same error happens on all of them... the only partial workarround I found is to use Unity-2d.

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.

Omer, with oneiric-proposed enabled there is currently no newer version of compiz. The most recent version is 1:0.9.6+bzr20110929-0ubuntu6. Didn't it build yet or do I have to reinstall this version?

@ubuntu-sru this upload of compiz can be accepted to oneiric-proposed since the new release of compiz would take a while. seb128 is aware of that.

Hello Fido, or anyone else affected,

Accepted compiz into oneiric-proposed. The package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

I've just test it with:

compiz-gnome amd64 1:0.9.6+bzr20110929-0ubuntu6.1
compiz-plugins-default amd64 1:0.9.6+bzr20110929-0ubuntu6.1
libdecoration0 amd64 1:0.9.6+bzr20110929-0ubuntu6.1
compiz-core amd64 1:0.9.6+bzr20110929-0ubuntu6.1
compiz all 1:0.9.6+bzr20110929-0ubuntu6.1

and seems to be working OK!

Thanks!

@Jean & Chris:
I have just checked it with my own application. It looks much better now, but there is still a problem if the popup is to open near the bottom or right edge of the screen.

Will try to debug this and report back then.

This bug also affects precise, since the fix is out it might be right moment to patch precice's version of unity too

I can confirm now that the fix works correctly.
The remaining problem I mentioned above is induced by some wrong calculations in my Java code.

I would like to emphasize that the fix above also solves a problem with wine applications:
Popups/popdowns have been misplaced, which was a new bug in oneiric. (Most often they popped up in the upper left edge of the screen).
This also works right now with the fix from oneiric-poposed applied.

With compiz pre-release 0.9.7 from didrocks PPA I am unable to reproduce this issue on precise.

This bug was fixed in the package compiz - 1:0.9.6+bzr20110929-0ubuntu6.1
