Something messed up MapsGL at http://maps.google.com/?vector=1 with this
configuration:

This is how the map looks http://imm.io/n1PJ street names are not visible. Same
garbled labels appear on Chromium.

At first I thought it was a bug on Firefox and reported it as
https://bugzilla.mozilla.org/show_bug.cgi?id=745481

Also reported it to the distribution (Ubuntu) as
https://bugs.launchpad.net/ubuntu/+bug/981883

Both bug reports suggested this was a problem "upstream" and suggested
I filed
the issue here so I'm doing that.

I see the same issue with r600

OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD JUNIPER
OpenGL version string: 2.1 Mesa 8.0.2
OpenGL shading language version string: 1.20
OpenGL extensions:

but sw works as expected.

OpenGL vendor string: VMware, Inc.
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x209)
OpenGL version string: 2.1 Mesa 8.0.2
OpenGL shading language version string: 1.20

suggesting the problem is in a more core component, possibly dri2-specific.
