Hello.

I am following the learningwebgl tutorial and have a problem:

http://learningwebgl.com/lessons/lesson05/

in this lesson, i see the textured quad for a while, but then, the textures disappear and instead i see this:

http://prntscr.com/7806l

It looks like it is using the texture coordinates as colors.

I have intel gma hd and this seems to happen only in firefox

can anyone help?

thank you. matej
