half screen artifacts on second link in bug report dialogue

[skyper]

1. get an exception
2. (switch user with gdm3)
3. (log out second user and switch back to previous virtual terminal)
4. move mouse on second link in bug report dialogue
5. wait 1-2 seconds

I get artifacts across the whole lower half of the screen instead of the link info.

Both other links work.
Do not know if this is caused by switching the virtual terminals or maybe gnome3.

If you are on testing, have you tried openjdk-7?

I did test on a different machine using the test files from #7266:

1. with openjdk-6 I got artifacts on all links
2. with openjdk-7 no problem the link info is show.

Can you please provide a link to the java bug report.

Thanks

I don't know it, sorry. But if it works with openjdk-7, it's not JOSM fault, hence the "othersoftware" resolution. Have you tried to contact openjdk-6 maintainers on Debian side ?

No, JOSM is written for java 1.6 not 1.7, or did I miss something.

Is it a debian bug or a java bug ?

I did not contact any maintainer as I did not know if JOSM source did change or if it was a bug introduced by a java update but if you can tell me that JOSM did not change or that it is working with other distributions I will definitly fill a bug report.

I have never seen such artefacts with openSUSE using Sun6 Java and openJDK6. Even if JOSM does something wrong (which I doubt) the result is in any case an issue with java or the windowing system, as a java application should not be allowed to produce such an error.
