UIBarButtonItem shifting downwards after a UINavigationController push

My app runs in a UINavigationController. When I push in a new view controller from the right, the top right UIBarButtonItem (Edit) shifts down by 1 pixel — the Edit button stays in place, but the graphic noticeable shifts down.

I've noticed this only happens after I set up a UIAppearance proxy for the bar button item. This is my code for doing that:

UIImage *barButton = [[UIImage imageNamed:@"navBarBarButton"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 5, 0, 5)];
[[UIBarButtonItem appearance] setBackgroundImage:barButton
                                        forState:UIControlStateNormal
                                      barMetrics:UIBarMetricsDefault];

navBarBarButton.png is a 52x31 bar button image.

Other potentially relevant info:

Has anyone seen this, know why this is happening, or how to prevent the button from shifting? Thanks.

I had the issue when font size was 18. After I've changed it to 19 shifting is gone and navigation bar transitions smoothly.

In case anyone gets here with the same issue, I managed to fix the issue by having my barButton image at the standard 30px height (instead of 31, as above).
