On this screenshot, you can see the first workspace in overview mode. The thumbnails of the applications are correct (firefox and terminal), but, in the background, you can see synaptic, which is actually opened in the second workspace and should not be displayed at all.

On the attached screenshot you can see that there are other display glitches (activities button with stranger colors) and white blocks over the synaptic title bar. My video card is an ATI Radeon Mobility using the open source driver. May all thos display problems be related?

Status changed to 'Confirmed' because the bug affects multiple users.

Changed in gnome-shell (Ubuntu):
status: New → Confirmed

Did you update from natty with the gnome3 ppa? I had the same problem, i could solve it by getting rid of my old settings

$ gsettings reset-recursively


I have an NVIDIA video card and besides from the display glitches, have the same issue in Oneiric.

I there, having the same bug, just posted a question about before finding this.

Here are my question:

For some more information, did a fresh install, not a upgrade.

I believe this is a duplicate of bug 875954 which appears to be caused by bug 838577 so I'm going to mark it as a duplicate.

Thank you for reporting this bug and helping to make Ubuntu better.

I don't even have a ATI vga and got this bug. I don't know if it is a duplicated.

Julien Olivier (julo) wrote :

I use the ATI open source driver. So, whether it's not a dup of bug #838577, or the said bug's summary is wrong.

Dewes, sorry about that. I meant to mark this as a duplicate of bug 848198.

I think you picked the wrong bug Jeremy :)

It should really be a duplicate of bug 875954.

Jeremy Bicha (jbicha) wrote :

This is a duplicate of bug 875954 which itself appears to be caused by the gconf bug 848198. Sorry again for the confusion.

Oh yes, sorry, I understand now.

This cannot be a duplicate of that bug. It says the bug is fixed and distributed, but I am fully up to date on my software and this behaviour still occurs. Using Ubuntu 11.10 64bit and gnome-shell. I've got an AMD VGA (HD5770) using open source drivers.
