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):
xorg-x11-drv-intel-2.20.8-1.fc17.x86_64
kernel-3.5.6-1.fc17.x86_64

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

Description: 
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

Hardware: 
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 16:32:24 UTC
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.

Comment 3 Robert de Rooy 2013-01-27 09:02:43 UTC
With recent updates the problem no longer occurs, as such closing this bug report.
