This is not a critical issue. I have a 24" 16:9 ratio LCD with 1900x1200. I'll expand the panel width all the way to %100. Then click on the site layout box just once. The whole site switches over to the boxes for a few seconds, but then just reverts back to the list view.
Interesting... at 1920x990 it works fine.
What is your rig update speed at? Also, have you tried another browser?
