Created attachment 415754 [details] Test The attached test is simply a <div> and this style: div { background-color: blue; position: absolute; left: 0; top: 0; height: 100%; width: 100%; } div:hover { height: auto; } When I move the cursor around the page the page flashes blue, as if the <div> stopped painting. This does not occur in either Firefox or Chrome.
