943433 - WebGL warning at wrong time

Status: RESOLVED DUPLICATE of bug 985316

(Core :: Graphics: CanvasWebGL, defect)

Description

[Patrick Cozzi]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/31.0.1650.57 Safari/537.36

Steps to reproduce:

Visit http://cesium.agi.com/Cesium/Build/Apps/CesiumViewer/

A new WebGL warning in Aurora (not in stable) is shown in the console:

"Error: WebGL: A texture is going to be rendered as if it were black, as per the OpenGL ES 2.0.24 spec section 3.8.2, because it is a 2D texture, with a minification filter requiring a mipmap, and is not mipmap complete (as defined in section 3.7.10)."

This appears to be triggered by the following call to bindTexture after the culprit texture.  I believe this does not conform to the ES 2.0 spec, which implies this warning should not occur until a call to drawElements or drawArrays.

The current warning limits an app's ability to work with textures, e.g., it assumes that all work will occur after one call to bindTexture.

This also happens on my machine.

The link appears to be broken, unfortunately.
However, I believe this is a duplicate of https://bugzilla.mozilla.org/show_bug.cgi?id=985316, which is now resolved. Please re-open if still seeing problems!
