I was using a downloaded osmesa32.dll before - is this still being used? About:support reports:

Aquarium demo is ok - it seems they had a JS problem on the site which is now fixed. Most WebGL stuff online now seems to work better. It is just the Body Browser from Google that seems glitchy

Your OSMesa is not being used anymore, you're now getting hardware acceleration directly from your intel driver. You probably want to update that if possible as it's a year old.

It's also possible the real problem is in some ANGLE bug, CC'ing bjacob.

OK. Just checked Intel site - the driver I have is latest version.

Also noticed sometimes when I refresh a WebGL, it is incredibly slow (software rendering?), then if I refresh again it is back to full speed. This is the case with any WebGL content

Hrm, so it seems :(. I didn't know Intel wasn't updating drivers on windows XP, that's a real shame.

In adittion to comment#9,
The problem does not happen if I set webgl.prefer_gl to true.

[Boris Zbarsky [:bzbarsky, bz on IRC]]

The bodybrowser issue sounds like bug 621718 or at least dependent on it.

Comment 12

[Benoit Jacob [:bjacob] (mostly away)]

Notice that the webgl.prefer_gl preference has been renamed to webgl.prefer-native-gl. It also is now created (false) by default.

Also, today I have updated ANGLE to r550, so there's a nonzero chance that these issues with ANGLE will be solved in tomorrow's nightly build.

Please reopen if this is still an issue. I cannot test on WinXP, but this is WFM on Win7.
