From the about:gpu:

NVIDIA Corporation
GL_RENDERER	Quadro K2100M/PCIe/SSE2
GL_VERSION	4.5.0 NVIDIA 384.90

Unable to reproduce this issue on reported version 63.0.3239.108 and on latest dev 65.0.3309.0 using Ubuntu 14.04 and Ubuntu 17.10  Mesa driver. 
 Navigated to https://www.shadertoy.com/view/Xljfzh and clicked on compile button and no driver crash is seen.

As ET team doesn't have Linux with NVIDIA driver, could soemone from Inhouse team take a look into this.

Thanks!

This can be reproduced on Windows as well with --use-angle=gl command line parameter. Seems to be an NVIDIA driver bug. I've reported this to the driver team and investigate a workaround for people running older drivers as well.

Here's a WebGL conformance test: https://github.com/KhronosGroup/WebGL/pull/2570

Fixed in NVIDIA driver version 397.31.

Thanks Olli for pushing to get this fixed!!!

Should we close this as WontFix?

technically, it's fixed. ;-)

It may not be too much effort to also implement a workaround for users with older drivers, I'll still look into that. If it looks like the workaround ends up too costly, then closing this as WontFix would be acceptable as well.

Rewrite repeated assignments to swizzled vectors on NVIDIA

This works around the most common instances of a bug that reproduces
on some NVIDIA OpenGL drivers prior to version 397.31.

The workaround handles most common instances of the bug for people still stuck with older drivers. Marking as fixed.

Add back some WebGL test expectations

A lot of expectations were removed but some of them were still
necessary, this adds them back.
