Comment 12 for bug 1314924

Note: The component may be Lib/Xrender but Driver/intel was chosen due to platform-specific issues.

This is the first of two bug reports I am filing, since the symptoms are distinct.

I am using Ubuntu 14.04 with an Intel 82865G.
I and a few other users encountered an issue in Firefox (also using certain Intel IGPs, various distributions) where a recent feature added to Firefox (essentially, an auto-disappearing forward button) causes text in the address bar to become obscured/replaced by rectangles: see link.

While the Firefox team is considering implementing their own workaround, the underlying problem is through Xrender, since the proposed workaround is to disable it in Firefox. I am adding this bug report to document this as an example, given the number of various corruption bugs out there, to see if this can be connected with others, feedback on additional information to collect, and possibly help to get a fix from Xrender.

Side note: documentation from Intel says that the video BIOS (aka VBIOS) is sometimes responsible for the corruption of graphics, however for most users the only way this can be updated is by a system BIOS update, which I know in my case is not available.

I am looking into a if it is possible to apply a VBIOS update e.g. using MEMDISK (from the SYSLINUX project) while in Grub2 (before booting Linux).
