Webgl2 regression (by comparing to webgl1?)

Issue descriptionSteps to reproduce the problem: On Samsung Galaxy S7 Edge (chrome 63 or canary, we didn't test beta) Visit https://sketchfab.com/models/109b3c7bfc09474cbd9ba0ddde45e3d6?webgl2=1 What is the expected behavior? We expect it to be the same as in webgl 1 : https://sketchfab.com/models/109b3c7bfc09474cbd9ba0ddde45e3d6?webgl2=0 What went wrong? Technical information (if it can be of any help): Because of skin shading, we are using a screenspace checkboard pattern that alternates one diffuse pixel and specular pixel. The screen only show specular, so it's likely the shader failed to reconstruct the diffuse part. So, probably a shader driver issue or a texture sampling one. Did this work before? No Does this work in other browsers? N/A Chrome version: 63.0.3239.132 Channel: stable OS Version: 7.0 Flash Version:

Sketchfab folks, can you provide us a small and simple test that highlights the difference between the shader execution on this phone and another one? We can easily spend all of our time triaging driver bugs like this one. We need your help to isolate where in the shader execution the bug is. Thanks.

The bug is not really critical for us (as we are still using webgl1, and we only reproduced the bug on samsung s7 Edge webgl2). So we don't want to spend too much time on it. I couldn't reproduce the issue with shadertoy and couldn't isolate a particular shader part either. (it's not that easy, because the checkerboarding code is spread along multiple pass : prepassZ forward, shading forward, postprocess SSS extraction, blurring and combining so..) https://sketchfab.com/models/d4ed1499ecf445c68bf19615d8b0a1c3 ^ Probably can't do simpler than that one way to confirm that the checkerboarding code is working correctly is to write in the "TextureSSSExtract" shader: if(gTexCoord.x>0.5) return vec4(diffuse, 0.0); return vec4(specular, 0.0); just after the call to : uncheckerboard(diffuse, specular);

I can't load any Sketchfab models on the Samsung Galaxy Edge S7. I was prompted to install VR Services which I didn't do and the following error is thrown in the console:

Sorry for the delay, I was on holiday. On the mobile devices we tested, models were loading fine without VR services (maybe a gearvr or s7 specific thing, we'll try to fix that).

Yup, I figured it was ARM rather than Qualcomm. Sorry, but I don't think we are going to get to this. We have too many bug reports to try to reduce each one. If you come up with a small test case, we will happily integrate it into the WebGL conformance suite. |
