[Bug 615779] [NEW] Thunderbird menus and dialog boxes are blank

[axx]

Public bug reported:

Binary package hint: thunderbird

lsb_release -rd
Description:	Ubuntu 10.04.1 LTS
Release:	10.04

apt-cache policy thunderbird
  Installed: 3.0.6+build2+nobinonly-0ubuntu0.10.04.1

Since updating to Lucid Lynx yesterday, Thunderbird won't load properly: the windows are mostly blank (reading pane), the submenus and the dialog boxes are blank (the initial "system integration" box for instance) and the menus buttons don't appear.
Apart from this, Thunderbird loads properly, downloads mail etc.

This is a on a two screen setup (laptop + external monitor).
Interestingly, on the external monitor, the Thunderbird window is
completely corrupted, on the laptop's screen, only the menus are blank
and the folder/account list and message list are readable.

This bug seems very likely related to bugs #564011 and #555382, though
in this case, the problem appears *without* any visual effects enabled
(System > Preferences > Appearance / Visual Effects set to "None" and
Compositing disabled in gconf-editor > apps > Metacity / General).

Also, this could have something to do with the infamous GMA500 "Poulsbo" graphics the laptop uses, the drivers of which are know for their high level of shittiness.
For this reason, I'll also attach the X.org.log, which might be of interest.

Let me know if I can add any useful information.

Thanks for your help, cheers :)
