Half transparent "Magnetic Disc"

Hello!

What I have done:
* I placed a "Magnetic Disc" on the drawing area (blue cylinder) and I went to its properties / Area / Transparency setting. Chose solid and set 50% transparency.

Expected behavior:
* A similar blue cylinder than the original with half transparency

Actual behavior:
* The lower half of the ellipse on top seems to be rendered twice. See attachment.

Regards,
Darabos, Edvárd Konrád

I see the problem in too. It occurs already in OpenOffice.

You can use the cylinder from the "Basic Shapes". It has a similar problem, that the upper part is not a transparent as expected, but there it effects the entire ellipse and that does not look so ugly.
