Hello, i got a strange problem using NGUI 3.0.6 f7 designing a UI for iPad (2048x1536 resolution).
Some sprites i'm using have one pixel "offset". I'm using UIToggle, e.g. with one "background" sprite and a "checkmark" sprite. Both images have the same size, both sprites the same dimensions and positions and using "Extract Sprite" gives me the correct images. Starting the application in the editor, the UI is shown correctly, too. However, when running the application on the device both sprites do not overlap correctly.
I attached an image which should (hopefully) explain the effect. The white line on the left side of the UI element should not appear (and does not appear when i run the app in editor, only on the iPad).
