Issue 614418  has been merged into this issue.

Can someone from ANGLE team take this bug? I don't have a local Windows machine with Intel GPU, nor do I have the bandwidth at this point.

Sure, that's fine. I think in this case we might want to deprioritize the fix or workaround if it's Intel-only. It's not clear that we'll be able to support fully conformant WebGL 2 on Intel Windows immediately.

Looking at conformance failures on Win / Intel HD 620.

We have the following expectations pointing at this bug (indirectly):

    self.Fail('deqp/functional/gles3/textureformat/sized_color_3d_pot_00.html',
        ['win', 'intel'], bug= 614418 )
    self.Fail('deqp/functional/gles3/textureformat/sized_color_3d_pot_01.html',
        ['win', 'intel'], bug= 614418 )
    self.Fail('deqp/functional/gles3/textureformat/sized_color_3d_pot_02.html',
        ['win', 'intel'], bug= 614418 )
    self.Fail('deqp/functional/gles3/textureformat/sized_color_3d_pot_03.html',
        ['win', 'intel'], bug= 614418 )
These still fail but so do many others in this category, so either this bug is hitting more tests or another bug is hitting all of them.

    self.Fail('deqp/functional/gles3/textureformat/sized_depth_stencil.html',
        ['win', 'intel'], bug= 614418 )
Still failing.

    self.Flaky('deqp/functional/gles3/textureformat/unsized_3d.html',
        ['win', 'intel'], bug= 614418 )
This one is NOT failing anymore.

CC'ing Yunchao, Qiankun and Yang from Intel's Web GPU team. I wonder whether we could collaborate to get these issues fixed, and WebGL 2.0 conformance runs clean on Windows with Intel GPUs?

FYI: I emailed the full results of my conformance run to the Intel Web GPU team for them to take a look (including these and a number of other failures).

Can you cc me on that email Kai? What GPU family were you using?

FYI. I tried to roll-in webgl CTS and run the tests on all bots. It seems to me that there were many failures for multiple GPU vendors. see https://codereview.chromium.org/2614313002/

Hi Kai:

Could you verify if these failures still occur on HD620 with the newly released driver 4590?

This issue has been Available for over a year. If it's no longer important or seems unlikely to be fixed, please consider closing it out. If it is important, please re-triage the issue.

Sorry for the inconvenience if the bug really should have been left as Available.

Intel team: could you please send a tryjob to win_optional_gpu_tests_rel which un-suppresses these tests and see whether they are now passing on the new Win/Intel bots? Thanks.

This failures are not existed in the webgl expectation file now. The failures were removed at this issue long ago: https://bugs.chromium.org/p/chromium/issues/detail?id=614418. 

Mark this issue as fixed.
