Chrome fails on deqp/functional/gles3/negativeshaderapi.html on nVidia Graphics card

Project Member Reported by qiankun....@intel.com, Mar 2 2016

Issue description

What steps will reproduce the problem?
1. open chrome with command line: --enable-unsafe-es3-apis
2. Open https://www.khronos.org/registry/webgl/sdk/tests/deqp/functional/gles3/negativeshaderapi.html?webglVersion=2


What is the expected output? What do you see instead?
The test should pass in WebGL 2.0 context.
But some tests fail.

This failure only appears on nVidia graphics card. It can passed on ChromeOS and Linux desktop with Intel graphics card. I guess there are bugs in driver about beginTransformFeedBack.

Note that there are some known failures in the es3fTransformFeedbackTests on NVIDIA's drivers which I'm working on suppressing, but I'd be surprised if they're breaking the es3fNegativeShaderApiTests. More likely there's a bug in Chromium's tracking of buffer or transform feedback state.

Hi ken, is there a bug tracking the failures your mentioned?

Yes -- Issue 526748.

I'll take this and look at it once the other transform feedback failures are suppressed.

This cannot be reproduced on ToT chromium and WebGL conformance test. Close it now.
