        <pre>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.
<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=1005501">https://bugzilla.mozilla.org/show_bug.cgi?id=1005501</a>

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).</pre>
