WebGL rendering bug on DX11 path (DX9 is fine)

Project Member Reported by evan....@gmail.com, Jun 20 2017

Issue description

Chrome Version: 58.0.3029.110
OS: Windows 10
GPU: Intel HD Graphics 530

What steps will reproduce the problem?
(1) Open the attached file

What is the expected result?

Running WebGL content in Chrome in DX11 mode should look the same as in DX9 mode.

What happens instead?

Running WebGL content in Chrome in DX11 mode has some bug that messes up the rendering. Running Chrome in DX9 mode works fine (i.e. doesn't demonstrate this bug). The attached file is a captured trace from a document loading in Figma (www.figma.com). We noticed this issue while testing our app Windows. Also worth noting: both Edge and Firefox also have this bug.

Please use labels and text to provide additional information.

It seems to be related to MSAA/CMAA issue, cc to Xinghua to keep an eye on this.
It is not MSAA/CMAA issue. It seems that one shader program(WebGLPrograms[7]) is failure to compile/link.

Appears to work now.
