Re: [Public WebGL] High number of failures in conformance suite

FWIW, The GMA X3100 is not supported on 10.8. (See https://developer.apple.com/graphicsimaging/opengl/capabilities/GLInfo_1080.html)

I wouldn't expect them to fair much better on 10.7.x either.  Our experience with the GL drivers on those cards hasn't ever been terribly great, and as far as I can tell, they've been effectively in maintenance-only mode for a few major OS revisions, so I wouldn't recommend trying to support WebGL on them.

I personally have not triaged the outstanding conformance suite
failures with Intel GPUs on Mac OS yet, and suspect that the other
browser vendors haven't, either.

Your user should upgrade from 10.6.8 to 10.8. It's unlikely that any
graphics driver bug will be fixed in the future on either the 10.6.x
or 10.7.x train.

Thanks very much for the advice. We don't yet know for sure that the suite
passes on Firefox yet. He didn't encounter the original issue within my
framework in FF, so hasn't tested the conformance suite in FF yet.

I've just requested that he run the suite on Firefox, and send the text
summary. Once I get that, I'll forward all the information on to the Chrome
tracker (and the Firefox one if there are a lot of failures there as well).

Thanks again,

The card is not on the list of unsupported devices of Chrome and the OS is
on the list of supported operating systems:

There are lots of errors around texture functions and glsl. I don't see a
clear pattern of where it fails other than some tendencies. I would post
this information as is to the chrome issue list
(http://code.google.com/p/chromium/issues/list) with a title like "webgl 657
conformance tests failed on OSX 10.6/GMA X3100"

There are 3 other issues where people have problems with the GMA X3100
- http://code.google.com/p/chromium/issues/detail?id=40825
- http://code.google.com/p/chromium/issues/detail?id=67558
- http://code.google.com/p/chromium/issues/detail?id=100781

I would mention in the ticket that the conformance works trough in
Firefox. The best hope to get to the bottom of this issue would be for a
chrome developer with OSX 10.6.8 and a GMA X3100 to try to replicate the
issue. Note that one possible outcome of this may be that the X3100 (or its
older 10.6 driver) will be blacklisted.

I had him run the tests again locally and here's what he had to say:

I ran the test locally with the SimpleHTTPServer and the results seem
exactly the same :

Tests PASSED: 3241
Tests FAILED: 657
Tests TIMED OUT: 31

Text summary of the tests : https://gist.github.com/3848167
Browser : Chrome 22.0.1229.79
OS : MacOS 10.6.8
GPU Model : GMA X3100
Driver Version : I really don't know about it. I just keep my system up

In order to be sure not to run into networking issues, the conformance
tests should be run locally.

Once the test have run, there is a button to "display text summary" of
the tests. Please collect the following from your user:
- text summary of the tests
- Browser/Version
- Operating System/Version
- GPU Model
- Driver Version

Make this information available here and we should be able to advise
appropriate next steps.

I apologize if this is the wrong forum for my question, and would
appreciate being directed toward the proper destination if so.

I'm trying to track down an issue a user of my WebGL framework is
experiencing, and in doing so, requested that he run the WebGL conformance
suite v1.1. He's running Chrome 22 on Mac OS X 10.6.8 with Intel GMA X3100
graphics. Here's his summary:

   Tests PASSED: 3241
   Tests FAILED: 657
   Tests TIMED OUT: 31

See https://gist.github.com/3840329 for the complete test results.

I have not yet asked him to run the conformance tests in Firefox,
because he has indicated that the original issue with my framework does not
appear in FF.

Given the high number of failures, what should I advise him to do?
Raise an issue with the browser vendor? Or, if this many failures are
expected for his platform, should I ignore them and continue working to
resolve the issue within my framework?

Not sure if it's helpful, but here's the issue as originally reported
to the framework: https://github.com/sinisterchipmunk/jax/issues/63
