Using the WebGL 1.0.4 conformance test on my Sandybridge laptop.

The other subtests are OK.

I'm using Mesa 1.8.1.1 on Firefox 60.0.2 Manjaro Linux (i've attached a complete glxinfo).
Comment 1 Tapani Pälli 2018-06-26 08:07:05 UTC 
These tests pass fine on chrome, this is likely bug in Firefox.
Comment 2 Denis 2018-07-03 11:04:30 UTC 
Agree with Tapani.

I checked latests released stable mesa version on ubuntu,

ubuntu 16.04
firefox 60.0.2 (latest)
chromium (66.0.3359.181)
mesa-version for FF (18.1.3 stable)
for Chromium (18.2.0 git-c7726fbfa5)

Results:

failed Mozzila (SNB, SKL)
passed Chromium (SNB, SKL)
_____
I would say that issue might be in FF browser.
