Seriously, you just really don't get it. Yes, if you close Safari in landscape mode, hold the phone in portrait and then re-open Safari, yes it opens in landscape as designed, and then switches to portrait. Then close it and open it again, and are you seriously telling me it doesn't stutter? Try opening and closing the Phone app and the Safari app and see the difference in the opening animation. Phone app is so smooth always, and Safari looks like crap after you've closed it in landscape mode the one time. It's lame, and I notice it all the time now, hah!
It's like trying to tell people their CRT monitor is flickering because it's set to 60hz, and they tell you they don't see any flickering.
I guess it's good that CRT monitors are rarely used these days.
Amino, I think it's time to move on. You're right, there's an issue with at least 4.1 (haven't test 4.2 yet), and there are those of us that see it and those of us that don't. What can you do? I see it, I agree with you, - I've tested this on 3 different phones, and they all do it.
But whatcha gonna do? The only "person? you need to convince of this problem is Apple.
