1313875 - WebGL2 demos crashing on latest Firefox Nightly on Windows10 / NVIDIA

Status: RESOLVED DUPLICATE of bug 1319004

(Core :: Graphics: CanvasWebGL, defect)

Description

[Andre Weissflog]

Attachment: DxDiag.txt

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:52.0) Gecko/20100101 Firefox/52.0
Build ID: 20161029062601

Steps to reproduce:

On a recent Nightly (version tested: 52.0a1 (2016-10-29) (64-bit)), on Windows 10 with a recent NVIDIA GeForce graphics card, go here and start testing the WebGL2 demos on that page:

https://floooh.github.io/oryol-webgl2/

Note how the Firefox tab crashes immediately. See attached DxDiag.txt file for more detailed system information.

The crashes only occured after I updated Nightly to the latest version, the previously installed 2..3 weeks old version worked fine.

A similar problem happens on Chrome Canary (don't forget to enable WebGL2 there), here's the related Chrome ticket:

https://bugs.chromium.org/p/chromium/issues/detail?id=660670

Since the crash happens in both browsers, may be it's related to a recent change in ANGLE?

Looks like an ANGLE issue.
