Status: RESOLVED WORKSFORME

(Core :: Graphics: CanvasWebGL, defect)

Description

[Loic]

Attachment: Screenshot FF10 vs FF15

Open WebGL demo "3D grapher" to plot mathematical equations in 3D:
http://www.webdev20.pl/skins/default/js/demos/3d_grapher/webgl_ploter.html

Surfaces are not rendered properly, they are pixelated and blinking instead of being smooth and static, like a kind of jamming was applied (see my screenshot).

Suspected bug:
Benoit Jacob — Bug 658826 - disable optimization in D3DCompiler to avoid freeze bugs - r=jrmuizel ANGLE's own buildsystem, which Chrome uses, has been doing this for a long time. This aligns us with them.

For what it's worth, that demo renders fine in Firefox 16 (beta) on my Windows NT machine with a Quadro FX 380.

Does another person confirm the issue?

Can we get an about:support dump?
Also, this works for me on Aurora 17.

...looks like I never clicked 'save changes'.
It still looks fine on Aurora 19:

I can't reproduce it anymore with FF17+. I close it.
