<div>
<pre>We found this issue when running WebGL 2.0 test as there is a case ported from
native dEQP. However, this also fails with native dEQP test.
Steps to repro:
1. ./deqp-gles3 -n
dEQP-GLES3.functional.shaders.derivate.dfdx.fbo_float_vec2_highp
Result:
This case fail. In fact, there are other 18 failure cases related with dfdx.
Notes:
We found these failure dfdx cases only exist on Broadwell machine. But these
cases pass on Skylake machine. And dfdy cases pass on Broadwell and SKylake
machine.
Are there some good reason to explain it, thank you.</pre>
