real_per, I can confirm every single screenshot you posted. I was just too lazy to do the same. They browser behaves exactly the same after a reflash with nothing installed. It's just messy coding.

The biggest issue is the page not loading properly. Just like you said, the page finishes loading and it displays nothing. It stays like that until you decide to scroll around a little which apparently triggers the rendering of the page. After a few seconds the page starts displaying. Really annoying and time consuming.
