1189742 - [Win10] Some WebGL games don't work properly

Status: NEW

(Core :: Graphics: CanvasWebGL, defect, P3)

Description

[Camelia Badau [:cbadau], Desktop QA]

Reproducible on Firefox 40 Beta 9 (BuildID: 20150730171029)
Mozilla/5.0 (Windows NT 10.0; WOW64; rv:40.0) Gecko/20100101 Firefox/40.0

Steps to reproduce: 
1. Launch Firefox.
2. Open http://www.3dsitelinks.com/webgl-games/. 
3. Open the following games: a) Barfight and b) FastKat2. 

Expected results: The games work properly and no issues occur. 

Actual results: 
   a) Barfight: loading state is persistent and user cannot play the game. 
   b) FastKat2: the game starts, but the initial menu remains on the screen while playing. The "In-game music off/on" option is not working.
 
Notes:
1. The games don't work properly on Firefox and Chrome, but work fine on Microsoft Edge. 
2. The issue is reproducible also on latest Nightly 42.0a1 (buildID: 20150730030208) and Firefox 39 RC Build 6 (buildID: 20150630154324).

Can you switch this machine back to Windows 8 or Windows 7 to see if this is a regression from updating to Windows 10? I suspect this might be more of an issue the developer needs to fix but we'll need more information to conclude that is the case.

I've reproduced this issue on a machine with Windows 10 clean installed, not updated from a previous Windows version.

Barfight loads for me on Win10 with Nightly 43, but some of the shaders don't compile, as dumped into its upper-left-hand corner text box.

FastKat2 seems to work without issues.

I've tested on Windows 10 64bit using latest Nightly 44.0a1 (buildID: 20150923030230), latest Aurora 43.0a2 (buildID: 20150923004024) and Firefox 41 RC Build 3 (buildID: 20150917150946) and the problem is still reproducible, as described in Description: 
  "a) Barfight: loading state is persistent and user cannot play the game. 
   b) FastKat2: the game starts, but the initial menu remains on the screen while playing. The "In-game music off/on" option is not working."
