Seems like the multitask screen does some sort of anti-aliasing on the application screenshots. If you enter the multitask screen, the current app open will not have the anti-aliasing. However, if you switch to another app and open the multitask screen again, the previous app will have the anti-aliasing treatment. Text and icons appears to be slightly blurred. Not sure if its visible in the image but the "Settings" text as well as the curves on icons should show the effect the clearest. Also, the anti-aliasing seems to help show the thin lines in the list that don't appear *It appears to happen on the iPhone 5. It might work on other devices as well. iPhone 4 & 4S doesn't seem to do that.
