I tried to resize the widget window to show you the problem, but somehow the picture get its properly size after I overcrossed a certain value for the width. The display mode changed when I switched from 150×188 to 170×188.
Mode at 150×180 -> Stretch:true
Mode at 170×188 -> Stretch:false
I just wanted to get Stretch:false mode and I didn’t know that it changes automatically. ??
So I think therere is no problem, if the display mode is addicted to the resolution.
