Questions about backgrounds

Hi all,

I make this topic to ask about backgrounds. When application is resized (to fill device's screen), quick background are incorrectly displayed. So far, I noticed the following problems:
- Constantly a quick background doesn't appear with a correct pattern. The pattern repeats sometimes till show a incorrect repetition, like a incorrect junction;
- Quick backgrounds are displayed in wrong position, displaced some pixels. If I have two quick backgrounds side by side, in Android will have a distance between them;
- Order don't work. Some backgrounds are positioned in wrong order in Android Runtime;

I took a picture. Please note the differences between the game in Android (first one) and in the PC.
