Unhandled gl errors: DCHECK(GL_NO_ERROR == glGetError()) when GPUTracer::ProcessTraces() is called

Project Member Reported by offenwanger@chromium.org, Sep 22 2017 
Chrome Version: 63.0.3222.0. (Official Build) canary (64-bit)
OS: Android 6.0.1 Samsung Galaxy S6

What steps will reproduce the problem?
Go to https://sketchfab.com/models/83ced347037f47aba8473147d65df074

What is the expected result? 
Application runs

What happens instead?
Application runs, but spits out 

[.Offscreen-For-WebGL-0x7f724f4a00]GL ERROR :GL_OUT_OF_MEMORY : GetShaderiv: <- error from previous GL command

Followed by a whole swath of these:

[.Offscreen-For-WebGL-0x7f724f4a00]GL ERROR :GL_INVALID_OPERATION : GetShaderiv: <- error from previous GL command

When running a debug build, this issue seems to cause this DCHECK to fail. 
https://cs.chromium.org/chromium/src/gpu/command_buffer/service/gpu_tracer.cc?q=gpu_tracer.cc&sq=package:chromium&dr&l=339

So far the issue seems confined to the Galaxy S6

Comment 1 by offenwanger@chromium.org, Sep 25 2017 

Tried a quick check to make sure this wasn't the function itself, if the DCHECK is moved to the top of the function it still fails, so the failure occurs somewhere outside that code.

Comment 2 by mthiesse@chromium.org, Sep 25 2017 

Not a duplicate of issue 682482?

It's also not super surprising that we might run out of memory on large sketchfab models.

Comment 3 by offenwanger@chromium.org, Sep 25 2017 

I don't think it is a duplicate. issue 682482 causes chrome to crash in production versions, whereas the only crash in this instance is when the DCHECK fails on debug versions. It might, however, be related.

zmo@, do you think this is a related issue?

Summary: Unhandled gl errors: DCHECK(GL_NO_ERROR == glGetError()) when GPUTracer::ProcessTraces() is called (was: Sketchfab triggering DCHECK on Samsung Galaxy S6)

I think this is caused by a bug in the implementation of the EXT_disjoint_timer_query extension on the Samsung Galaxy S6 and that we should disable this extension on that device. See  Issue 702980 .

 Issue 702980  has just been closed as fixed by virtue of disabling the EXT_disjoint_timer_query extension on this device. This should cause Sketchfab to no longer attempt to use it and the problem to go away. I'm duplicating this into the other report. Please test with Chrome Canary once it contains the fix and reopen this bug if it's still happening. Thanks.
