Details

The checkerboard detection hacks we use in Eideticker aren't really working in the modern age, where we substitute low-resolution tiles when we haven't completely drawn a region while scrolling: http://wrla.ch/blog/2013/03/eideticker-limitations-in-cross-browser-performance-testing/ :jchen had the interesting of idea of analyzing the capture for frequency content, so we could detect which browsers had sharper images (sharper images should tend to have higher frequency): http://wrla.ch/blog/2013/03/eideticker-limitations-in-cross-browser-performance-testing/comment-page-1/#comment-7202 This should work across browsers too, no matter what checkerboarding algorithm they use.
Eideticker has been discontinued, see bug 1361056
