Serious kudos to the author for posting this even though he mentions viewing pornography.
I had a similar problem on iOS. When I load Safari, there's usually a flash of the previous screen (probably cached as a PNG), then the page loads. I think it looks junky; I'd prefer a "loading" screen. It would flash the previous screen whether I was in private mode or not. So porn would flash on my screen. I didn't file a bug report or mention it on my twitter because I'm a little afraid of the reception. So, again, thank you charliehorse55.
edit: i said "cached as a PNG" but that's just what I thought prior to reading this article. it could be many things, including this bug.
That is indeed "cached as a PNG." iOS caches previews for the multitasking switcher. Sometimes I could see screenshots of pages that were opened a month ago.
Apps like 1Password make their screen blank when they go into background to prevent this… Firefox for iOS does this too!
I've seen that too, sometimes the tab previews in the tab overview often show outdated thumbnails even if you wait a while - it never settles to the correct thumbnail.
This seems fixed in iOS 9 - if Safari is in private mode, the 'screenshot' for multitasking/restore is of empty page.
My e-banking does the same thing - as it requires password when switching back into tab, they show just a big bank logo to hide your account history from multitasker.
I also wear gray shirts and occasionally listen to ska.
Nothing makes people quite so alien as differing moral codes. I'm "showing my hand" as regards something that simply does not matter to the majority of people on this website. Trying to make a big deal out of it simply makes you look strange.
