Java corrupts xserver or nvidia module

[Shinji]

Hi!

Since Kubuntu 9.10 I have a strange bug.
Every time I start the java application "JDownloader 0.89 " with the following command, I get a lot of graphic glitches on my Dektop. I don't know what package is affected... x-server-xorg oder nvidia-glx...

I uploaded a video to youtube, so you can see what happens when I try to start JDownloader:

Can you remove every nvidia package, restart X and test again ?

[Ludwin Janvier (lud-janvier)]

from duplicate bug :
"when i deactivate nvidia drivers in X its working."
I presume this is the case here too.

Hello,

Same issue here, with latest version of JDownloader (9.310), Asus P5E3 Deluxe mobo, Nvidia GeForce 9500 GT with v185 driver installed through the provided proprietary drivers management tool. Linux distro is a vanilla Kubuntu v9.10 AMD64 (installed a few days ago).

I can report that this issue could lead to a complete crash of the box. When I'm lucky, I may fall to a text console (ctrl-alt-F1), kill java and get back to KDE. All corrupted bitmap caches remain corrupted in that case, what can be fixed by closing/reopening my user session.

I cannot tell if the issue is with java or with JDownloader, as I haven't had the time to try another Java application so far. And I won't have today.

Finally, yes, not using the nvidia driver solves the issue for me. But it's a high price to pay.

Installing the latest vertified nVidia drivers (190.42) seems to fix the problem, suggesting that its origin is in an interaction between the linux kjernel, java, and older versions of the nVidia driver. I'll stick to this solution until an updated nvidia driver package is released through the regular Ubuntu channels.
