I've changed NGUI's Example Scene "ScrollView(Panel)" to use a
Sliced Sprite for the items instead of the simple ones. The
Filter Mode of the corresponding atlas texture is set to
Point. The following animation illustrates that those items won't be rendered pixel perfect:

Please note that I have a real problem with this issue in another application. I only took the Example Scene to explain my problem for easier reproduction. The versions of my software: Unity 4.5.1f3 and NGUI v3.7.5
Does anyone know how to fix this problem?
