STR:
1. If your testing the in-content prefs panel, turn it off.
browser.preferences.inContent  set to 'false'
2. Open a few tabs, I'm currently using 10 tabs 
3. Open the Options Panel (the one that now should show the old style module panel)
4. Several tabs (varies, 5-6 here) will loose text/favicons
5. Close the Options Panel and missing items may return, or mousing over the tabs will 
restore the text/icons.

Tested on win7 x64 latest hourly win32 m-c build based on cset:

This is likely different from this bug.

Only if you have manually set gfx.content.azure.enabled could this bug be related. But yesterday this could've definitely been related. Today it should be fixed.
Reference comment #3 you want me to spin another bug with same STR.  Commnet #0 didn't really specify what sort of screen corruption he was seeing.

That's probably best, I'm trying to reproduce it now.

I can reproduce this, almost definitely a different bug!

Can you still reproduce the issue with latest version with clean new fresh profile without any addons and plugins?

This pref was removed some time ago and replaced with pref: layout.paint_rects_separately
a 'hidden pref' 

Setting the value =2 fixed the issue for me...

this bug should probably be closed, with WFM or WONTFIX since there have been many changes since this bug was created.
I don't think so, as "layout.paint_rects_separately" is boolean type of preference and correct values are only "true" and "false"

oops! your right, I was thinking of pref:  gfx.font_rendering.cleartype_params.rendering_mode  setting that to '2' as I recall was part of the 'fix' for bad looking fonts.

Still, the original pref is deprecated, and this bug should be closed IMO.
