True.  That was rather tangential.  It is one of the (important) factors
in whether to block a graphics card by default, though.  Anyway, as you
say, not really important right now.

Absolutely.  Yes, the brokenness is something we need to look into.  As
you say, most users will have no way to use opera if it comes up like
this.

Thanks.  I'm currently pretty blank though.  If I think of something,
I'll let you know.

Hmm.  You'll have to enlighten me.

WebGL will use HWA, even when HWA is turned off.  But it might still be
interesting to test and see whether that breaks in the same way.

Hmm, I generally test with some of the stuff on alteredqualia.com.  Some
of these usually works reasonably well:

http://alteredqualia.com/three/examples/geometry_colors.html
http://alteredqualia.com/three/examples/ribbons_gl.html
http://alteredqualia.com/three/examples/webgl_shader_lava.html

While I think it should be pretty obvious whether they work or not, I
believe these also work in both chrome/chromium and firefox/iceweasel
(assuming you can get those browsers to do webgl, of course).

I'm intrigued.  What's the difference?
