I just upgraded from AT 7.x.-1.0 to the 2.0 version. I'm using a fixed layout width for now. In Chrome on my Mac and in IE in Windows, I noticed some images were rendering strangely (squished to a small size).
I found this rule in at.base.css to be the cause,
/* Enable responsive images */
Resetting the value to a max-width:none fixed my issue. I guess I'm just wondering if there's a better approach, or if I'm missing something. I suspect this rule is there to take advantage of the new Responsive Design styles with AT 2.0. But if I'm not ready to use those just yet, or at least not ready to use those on my computer screen, so what to do?
