Java application windows cut-off/truncated/not displayed properly

[Ingo Gerth]

How to reproduce:
1. Install a JAVA application. In my case, I am running Matlab 2011a.
2. Open it.

What should happen:
Show a nicely rendered window.

What happens instead:
The window is not properly shown and cut-off at the bottom and right hand side. There are also strange artifacts and the Nautilus selection tooltip is displayed in the lower right corner. This is a regression from 11.04.

Recommended importance:
High. This bug prevents deployment of Ubuntu 11.10 to academic institutions, because widespread, high value software can not be executed properly. This includes e.g. Matlab, Maple, etc.

Another screenshot. Note that I couldn't post the bug upstream.

Thanks for the report. I'll be working on this next week.

I can't reproduce this with all the java apps I've tried. I'll get a hold of MathWorks today and try to get an evaluation build of matlab

 > Thanks for the report.

Don't mention, clearly you are the one to be thanked here! Keep up the great work, I really appreciate your effort.

It's odd that you can't reproduce the bug. I'll have a look at it today again.

racarr says this is fixed in the oneiric branch with applications like CGoban from gokgs.com . Can you check if you can reproduce the bug with that application as well? If so, then I'm willing to bet that this is probably fixed somehow [tm]

[Sam Spilsbury (smspillaz)]

(To clarify, he mentioned that he got this same bug with that application 2 weeks ago and now no longer gets it with an up to date trunk)

[Ingo Gerth (igerth)]

It is indeed fixed, Matlab works like charm again. Cheers!
