screenshot with severe glyph corruption

Description of problem:
ThinkPad T410 with Intel IronLake graphics

Using the Switch User function in Gnome, causes Glyph corruption.

Version-Release number of selected component (if applicable):

How reproducible:
The corruption may not be instantly noticeable, it may take a switch or two to occur. Also, it does not seem to effect the Gnome Shell itself, but it does effect Firefox and terminal windows.

Steps to Reproduce:
1. Login to Gnome Shell
2. Switch User
3. launch firefox and browse a bit
4. Logout
5. switch back to the first user
Actual results:
Glyph corruption. Severity of the corruption depends, sometimes it is minimal, other times it can be quite severe.

Expected results:
No glyph corruption

Additional info:
This corruption was introduced with an update along the way, as I did not experience it on F17 without updates.

There are no errors in the kernel or xorg log files

Same kind of problem here, corrupted glyphs (or disappearing glyphs) with Firefox and Terminal, but also gedit. Problem appears progressively, but faster when locking screen or suspending a lot.

Version-Release number of selected component (if applicable): 
xorg-x11-drv-intel / x86_64 / 2.20.8 / 1.fc17
kernel / x86_64 / 3.6.3 / 1.fc17

Integrated Intel GMA X4500 GPU 

Additional info: 
I think also that I was not experiencing this glyph corruption a few updates away. But a few updates away, I was dealing with another bug in xorg-x11-drv-intel, "Bug 845803 - wrong monitor resolution on wake from suspend with kernel 3.5.0-2.fc17.x86_64" <https://bugzilla.redhat.com/show_bug.cgi?id=845803>.
Comment 2 Jean-Philippe Leboeuf 2012-11-20 11:32:24 EST
Nomore problems at this time...

Version-Release number of selected component (if applicable): 
xorg-x11-drv-intel / x86_64 / 2.20.10 / 2.fc17
kernel / x86_64 / 3.6.6 / 1.fc17

I do not know if it's linked, but I get blank text with Firefox inside the URL dropdown of the navigation toolbar, from session start.
