Hi,

It happens on various websites I visit, like eurogamer.net or gamingonlinux.com. There are usually other apps running, though (meaning: the phone's been up for a while) and it looks like it's closing them, because they take their time to load when switching away from the browser.

Anyway, I just did a little test: I rebooted the phone and started reading eurogamer. Within 3 minutes I got the white screen, while loading comments to an article on the front page. Is there a way I can tell what the reason for the disappearing renderer was?

They have a mechanism on the comments page which loads in new comments at the bottom after reaching a certain point down the page; I've had it go white a couple of times while it was doing that. Also, it can occur while I'm just quickly scrolling through a lot of comments.

Generally, eurogamer is a problem site for the web browser, but that's a matter for another mail.

I will, thanks.
