Persistent white bar in upper left

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue for you. Can you try with the latest Ubuntu release? Thanks in advance.

Yes, it's still an issue, and no I can't upgrade my distribution (took long
enough to get things up and running once!). Sorry... -Damian

How about testing a Live CD to see if the issue goes away? No need to upgrade, just want to test to see if it is something in your profile, as you stated it followed you from 7.04 to 8.04. Curious if when you boot off a Ubuntu 8.10 Live CD if you still see the same behavior. If you do, then I would think this bug is video card specific, so I could move it under xorg. Thanks for the follow up, and any further information you can provide.

Sorry, haven't had time to check a live boot but as mentioned this seems to
be an application issue. It doesn't manifest on boot and it always occurs
under the following conditions:
- Running VLC
- Running IcePodder
- Browsing to certain sites (like GMail) in Firefox, but not for others

My guess would be an issue with a common ui library. It's probably not GTK
(the problem doesn't appear for Gnome games for instance) but I'm suspecting
the wxPython library (it's used in both VLC and IcePodder, and possibly
Firefox plugins). Do you have any idea how to test this? -Damian
