Thunderbird/Firefox rendering without borders and scrollbars

[dircha <dircha@dircha.com>]

After resuming from suspend-to-disk (ACPI sleep state 4), Thunderbird 
(mozilla-thunderbird in sid) and Firefox (mozilla-firefox in sid) render 
their interfaces without borders and scrollbars. Both applications 
otherwise function correctly.

I'm using the default themes for both applications (whichever is 
installed by default), and the default theme for gtk+ (whichever is used 
when you have no theme packages installed).

Dialogs which popup in the applications also are rendered without 
borders. However, default submit-style buttons are rendered correctly 
once they have been activated by moving the mouse over them. As are 
scrollbars.

Restarting the applications does not solve the problem.

Executing xrefresh does nothing either.

Resizing and similar operations have no effect.

However, rebooting does solve the problem. Obviously this is not an 
ideal solution, as I use suspend-to-disk to avoid rebooting.

I'm not sure just how to figure out what is going wrong here. Is there 
some way to force a library to be reloaded from disk?
