Comment 6 for bug 902594

Christian noted that he validated that problem is the continuous redraw events that are occurring. But does webkit think that it should continously redraw? Could it be a resource cacheing issue in Webkit? If there is a cache error that never updates the expiration time of page resources then as soon as the user selects a tab the faulty cache code sees an expired webview and redraws. After redraw the event engine sees the expired resources again and does a redraw.

Let me check and see if forcing a manual reload of the page properly updates any resource expiration time.
