        <pre>Hello, I have an 82852/855GM graphics chipset and I'm using Linux Mint 13.

I'm encountering two annoying problems:  The first is when I try to use the
Cinnamon-3d desktop environment, and the second problem involves GLX-dock.

Incorrect (white color) drop shadows drawn underneath windows.  I have detailed
this problem, as well as my system hardware/kernel/driver specifications, as
best as I could in the Linux Mint forum below.  I have also provided a few
screenshots in that thread.:
    *<a href="http://forums.linuxmint.com/viewtopic.php?f=208&t=136419">http://forums.linuxmint.com/viewtopic.php?f=208&t=136419</a>

A strange white rectangle, the size of the entire dock appears whenever I
show/hide the GLX-dock (using the OpenGL backend).  For this problem, I've
uploaded a short YouTube video to show exactly what I'm talking about as it
happened.:
    *<a href="http://www.youtube.com/watch?v=nD9VV38xA4M">http://www.youtube.com/watch?v=nD9VV38xA4M</a>

I should point out that whenever I show or hide the GLX-dock, I get this
terminal output:

------
warning : 
(build/buildd/cairo-dock-3.3.99.alpha1.1-20131204~bzr1685/src/implementations/cairo-dock-hiding-effect.c:_pre_render_opengl:53)
  FBO not ready
------

I know/believe the 82852/855GM chipset is at least more than capable of
handling something as simple as a dock and drop shadows.  Is there anything I
can do</pre>
