Description Zhenya 2013-09-08 00:20:10 UTC
The input field inside EntryElement is created with an incorrect frame which causes image distortion on iPad 2 (at least). The problem is that frame's y coordinate is not an integer. Here is how it is calculated (MonoTouch.Dialog/Element.cs):
float yOffset = (cell.ContentView.Bounds.Height - size.Height) / 2 - 1;

I believe it should be like this instead:
float yOffset = Math.Round((cell.ContentView.Bounds.Height - size.Height) / 2 - 1);

You can see the distortion especially well if you turn on Color Misaligned Images option in the Device Emulator.

Looks like this is no longer happening as you can see in the image attached in comment #3 with color misaligned images option enabled in the iPad emulator.
