blur

Why would the default iPhone interface elements, specifically the UISwitch (unmodified) and a UISegmentedControl appear slightly blurred? I have not changed them or called any private APIs. This blurring occurs when I run it both in the simulator and when I load it on my iPod Touch, so I don't think it's a one off drawing glitch. These elements were created via some code (initWithFrame:) not in interface builder. Here is a screenshot of the blurring in the simulator: http://drp.ly/14rS6a

It looks similar on the actual device.

Thanks for your help
