        <pre>Hello,

Firstly, thank you for developing these open-source drivers!

I'm part of the Cairo-Dock [1] team and many users have visual problem when
using the OpenGL backend: icons disappear.

All these users have an Intel 4000 HD Ivy-Bridge video card.

This bug has already been reported to Mesa devs (6 months ago) but this bug has
still not been fixed: <a class="bz_bug_link 
          bz_status_NEW "
   title="NEW --- - [Intel HD 4000] [Ivy-Bridge] Cairo-Dock's icons disappear when using OpenGL backend (GLX-Dock)"
   href="show_bug.cgi?id=55036">bug #55036</a> =>
<a class="bz_bug_link 
          bz_status_NEW "
   title="NEW --- - [Intel HD 4000] [Ivy-Bridge] Cairo-Dock's icons disappear when using OpenGL backend (GLX-Dock)"
   href="show_bug.cgi?id=55036">https://bugs.freedesktop.org/show_bug.cgi?id=55036</a>

On this bug report, you can see a video with the problem:
<a href="https://bugs.freedesktop.org/attachment.cgi?id=67303">https://bugs.freedesktop.org/attachment.cgi?id=67303</a>

I report this bug here because it's maybe not due to i965 Mesa drivers.
How can we help to debug the problem and how to know where the problem comes
from?

Regards,

Matt
