Hi Julius,

Not sure how much help I'll be, but I looked at the screencast and 
going through it frame by frame, it looks as though the "weird lines" 
are shadows (inner shadow, not a drop shadow) from the bounding 
rectangle of the icons. You see the same effect from the bounding area 
of the "Öffnen" text. (See halfway through the screencast)
I can't explain why they only appear sometimes either.
