[Solved] Nifty GUI backgroundImage Quality

My Problem is that the quality of the images is far worse then in image editor:

How I can improve the quality?

<control name="button" id="start_button" backgroundImage="Interface/Buttons/play_btn.png" style="menu-button" height="30%" width="100%" valign="top" childLayout="center"> <interact onClick="nextScreen(name_enter)"/> </control>

Hm, okay. I found the source of it:

AppSettings settings = new AppSettings(true);

I thought it would use desktop resolution instead of default 640x480 :persevere:
