Minimal presentation to reproduce the bug.

Area transparency does not work properly in presentation mode. Simplest way to reproduce (see also attachment):
1. Create a rectangle on top of some text
2. Fill color: white
3. Choose transparency 50%. Rectangle is correctly displayed (Normal view).
4. Switch into presentation mode: The rectangle appears in transparent gray, not transparent white (if you choose a different fill color, light red for instance, the transparency also seems to translate into a gray shaded red).
5. There is a way around the problem: Choose a linear transparency gradient with start value 50% and end value 50%. Funnily, the rectangle is fully transparent in Normal view, but appears 50% transparent (white) in presentation mode.
