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.

Hi,
I am implementing something like a coverflow. So I have many visual
elements
in the background and one which is closer to the user and in focus.
I put a transparent layer on top of the background elements, which
makes
them darker. This is very good to make the user focus more on the
element in
the foreground.
I had applied additionally an backgroundFilter to this transparent
layer
(CIGaussianBlur. CIBoxBlur ... tried both). This effect is so great
I really
want it in my product.
The problem is that some weird lines appear when other layers are
drawn in
my scene.
Did a short screencast to make this more clear:

Has anyone an idea , why this is happening and how I can fix it?
BTW: its a quicksilver interface called "silverflow", already
available as
beta on my website www.jeckert.net.tc , freeware
Thanks in advance,
Julius
