Attachment: Zip archive with correct and incorrect rendering on Firefox10, also system log

User Agent: Mozilla/5.0 (Windows NT 5.1) AppleWebKit/535.7 (KHTML, like Gecko) Chrome/16.0.912.77 Safari/535.7

Steps to reproduce:

Browse to some WebGL sites (only samples shown below) - on Windows XP, with Intel integrated graphics (log of system info attached). Monitor resolution is 1440x900.

http://rinesh.in/lab/airhockeywebgl/ (from http://www.chromeexperiments.com/detail/webgl-air-hockey-demo/)



Actual results:

) Positioning of canvas within the browser window is not correct

2) Width of canvas is not correct and is larger than expected (wrong_firefox10.png, wrong_firefox10_gpupowered.png)


Expected results:

1) Canvas should have been positioned correctly

2) Width of canvas should be lesser (refer to correct_chrome_firefox9.PNG, correct_chrome_firefox9_gpupowered.PNG)

This is functional on Firefox previous versions (9.x) and other browsers like Chrome.

Bug present in Firefox 10, but Works fine in Firefox 11 again. Not yet found the culprit, but closing it.
