980285 - Antialiasing is not supported in WebGL canvases in OSX.

Status: RESOLVED INVALID

(Core :: Graphics: CanvasWebGL, defect)

Description

[Jukka Jylänki]

Attachment: test_antialias.html

Firefox does not support antialiased WebGL contexts in OSX.

1. Open the attached page. The page tries to create an antialiased WebGL context.

Observed: The page prints "Antialias supported by canvas: false"
Expected: The page should report "Antialias supported by canvas: true"

Tested on latest Macbook Pro, where the page properly reports true in Chrome 33.

Which version of OSX is failing, because on 10.9.2 I get true.

We need to get more OSX versions into TBPL.

We actually just removed 10.7 slaves a few months ago. This should be caught by just having 10.6 and 10.8, so I don't think having 10.7 slaves would help us much. (one of the reasons they were removed)
