Build Identifier: firefox 4.0.1

I made a shadow webgl example.
I know that it can be tricky because of Angle and there is chance it's related. btw, the program works perfectly on linux (chromium and firefox). On windows7 it works for chrome but not for firefox, it produces weird visual glitch.

Reproducible: Always

Steps to Reproduce:
1. open this url on firefox 4.0.1 on windows 7 http://osgjs.org/osgjs/examples/shadow/index.html
2. open the same page on firefox linux, it works
3.


Expected Results:  
the behaviour should be the same on both plateform
Component: Tabbed Browser → Graphics
Product: Firefox → Core
QA Contact: tabbed.browser → thebes
Version: unspecified → 2.0 Branch
after testing again it seems to works sometime on chrome but most of the case it produces a glitch too (chrome 11).
What do you see on Windows?
Attached file the full example
Some extra informations with screenshoots, version ...

I have nvidia driver 270 series with Quadro FX 880M
Windows7 64 bits
chrome version: 11.0.696.68
firefox 4 version: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0.1) Gecko/20100101 Firefox/4.0.1

to run the example go in example/shadow and open index.html

the screenshoots with nativegl are what is expected
to produce the screenshoots with native gl I did:
for chrome I ran chrome.exe --use-gl=desktop
for firefox I have enabled it with about:config force native gl

http://code.google.com/p/angleproject/issues/detail?id=157 seems to have been fixed in canary build of chrome with a recent revision of Angle.
I have tested yet
Then that will be fixed by bug 657748
Depends on: 657748
Should be fixed by the ANGLE update, reopen if needed.
