I've begun to roll out the Responsive Adsense Unit (which loads asynchronously). Tonight I noticed something very peculiar. When I view it on my iPad (landscape mode), the ad looks perfectly fine when my tablet is lying flat. But as I increase the angle of the iPad (such as going to a 30 degree angle for better viewing), the ad gradually begins to move to the left and partially disappears! The amount of pixels it moves is about 20-30 pixels when the iPad is moved to a 90 degree viewing angle. Also, I'm not changing the orientation of the iPad any...just the angle of viewing.
Meanwhile, if I change the orientation to portrait mode...the ad will move "to the right" by about 10-20 pixels as I change the viewing angle. The ad again displays perfectly when lying flat, but as I change the viewing angle the ad slowly moves to the right...and again partially disappears.
Has anyone else noticed this...or am I just unlucky? Or is something perhaps wrong with my code that is causing this very peculiar behavior?
Edit : I'm seeing this problem using the Safari browser on an iPad 3 (first-gen retina display model). On my iPad, Chrome doesn't seem to have this issue. Also, the Adsense Responsive Unit displays fine on FF, IE and Chrome on my laptop, even when the browser windows viewport is reduced to tablet mode.
So this might be a strange Safari bug?
