Assigning to kbr for triage.  Is this something that should ever be fixed?

Yes. Yang, Yunchao, could you please investigate this? It looks like a potential bug in Mesa. Maybe it's already been fixed.

I had tested this case on local machine(Ubuntu 17.04) with Intel HD 630, and could not reproduce it now.

Thanks Xinghua for checking. Would you prepare a CL removing the suppression for the Linux Intel HD 630 bot from webgl_conformance_expectations.py and webgl2_conformance_expectations.py?

Hi, kbr, We reproduced this issue on Broadwell machine and submitted a bug to mesa team ago, https://bugs.freedesktop.org/show_bug.cgi?id=99108, then mesa team did not provide a solution.
Now could not reproduce this issue on three platforms(coffelake with HD630, skylake with HD630 and broadwell with iris pro graphics 6200).
I do not ensure that mesa had fixed it, but I submit a CL to remove suppression, https://chromium-review.googlesource.com/c/chromium/src/+/1195113

Thanks Xinghua. Let's integrate your CL which removes the suppression for our bots.
