Blank display for some Web
GL games (Could not initialise shader error)
Reproducible with: - Firefox 35 Beta 5 - BuildID: 20141218174327 - Firefox 36 Aurora latest - BuildID: 20141217004003 - Firefox 37 Nightly latest - BuildID: 20141218030202 NOT Reproducible with: - Firefox 34.0.5 Reproducible on: Windows 7 x64, Windows 8.1 x86 (AMD and NVidia cards) Works on: Mac OS X 10.7.5, Ubuntu 14.04 x86 Steps to reproduce: 1. Open Firefox and load the following WebGL games: http://oos.moxiecode.com/js_webgl/monster_truck/, http://racer.nomo.hu/. Expected results: The games load, and can be played. Actual results: The games load but cannot be played as display is blank. Error "Could not initialise shader" displays in the console. See full console logs at: http://pastebin.com/FKw3ZZtr, http://pastebin.com/Ji72B2gq. The issue reproduces the same way on IE and Chrome, but at the same time is a regression from 2014-10-10: Regression window(m-c) Good: 2014-10-09 (BuildID=20141009030201) Bad: 2014-10-10 (BuildID=20141010030201) Pushlog: https://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=5d6ec4dddf14&tochange=50b689feab5f The main suspect seems to be https://bugzilla.mozilla.org/show_bug.cgi?id=1076020. This may be the same issue as bug 1113633 (but this bug only reproduces on Windows).
Milan, can we get someone to look into this?
Jeff, game side error, and we're just tougher on them?

Same as bug 1113633, we might want to make a note of this (if it is on our side) since there's nothing ready to land on Beta 35 and we're very late in the cycle.
Without actually dumping the shader sources, this looks like it was broken by us correcting our implementation: The precision of uniforms must match in all shaders at link time.
