JavaScript warning: https://bug1228711.bmoattachments.org/attachment.cgi?id=8693165, line 11: Error: WebGL: texImage2D: Unexpected error during upload: 0x0501
texImage2D: dui: 1908/1908/8033
Assertion failure: false (Unexpected GL error.), at /Users/bgirard/mozilla/mozilla-central/tree/dom/canvas/WebGLTextureUpload.cpp:1130
0x0501 = GL_INVALID_VALUE
0x1908 = GL_RGBA
0x8033 = GL_UNSIGNED_SHORT_4_4_4_4
What should webgl be doing with these values?
Flags: needinfo?(jgilbert)
I am stunned that this isn't tested. It's an INVALID_VALUE because it's a cubemap texImage specification that's non-square.
