[Bisected]. WebGL2 conformance regression: deqp/functional/gles3/shadercommonfunction.html
Environment: Ubuntu 19.04, Intel UHD630
Steps:
- Download Chrome canary from https://www.google.com/intl/en_us/chrome/dev/?platform=linux
- Start Chrome with the command line option: --use-gl=angle
- Open page deqp/functional/gles3/shadercommonfunction.html
Result: Several test cases failed (such as common.isnan.float_highp_vertex)
Notes:
- This bug is a Mesa regression. It passed on Mesa 19.1.7, but failed from 19.2.1 to latest master branch.
- This bug can only be exposed if ANGLE is used, and it was recently turned on by default.
