Since DLBI landed we're repainting the whole page very frequently on mobile on small pans where previously we retained the content. I can reproduce this on cnn.com and http://taskjs.org/. This is a large performance regression for mobile:

http://graphs.mozilla.org/graph.html#tests=[[175,63,20],[201,63,20]]&sel=none&displayrange=7&datatype=running
Regression linked above is 4000% (40 times)
Summary: Over painting in mobile → increased over painting in mobile with dlbi
