During a slide show mode center x/y parameters of area transparency seem to be ignored. A test presentation and a screen shot attached.

I am having problems reproducing on LibreOffice 3.4  340m1(Build:103) for OpenSuse Linux. When I download your attachment, this is what I see:

Gradient transparency for the slides with "test" on the center. Transparent in the bottom right corner. When I enter slide mode, the transparency is an oval in the center, which matches your screen shot exactly. I am about to confirm, but...

When I create my own rectangle shape and apply transparency gradient, it appears as it looks on slide view mode. Also, when I edit the style of the text box on the sides and enter text into it, it works fine as well. I am not sure of what you did to your shapes, but you give us the steps? That would be great. Here is how I did mine:

1. Insert a new slide
2. Edit the ready made body text box and right click, edit style.
3. Select Transparency, select gradient
4. Choose any configuration of color, direction, and percentage.
5. Once done, enter text into the text box
6. Press f5 for slide view

You can do the same with shapes. Maybe there is something different with the shapes you created? Because when I download them, they have the same problems that you pointed out, but when I create my own, they seem fine.

First of all this is a regression problem. First I noticed it on presentations prepared with Impress version 3.3.* and opened on my colleague's MacOS with 3.4.

So I installed current vanilla version 3.4.1 on my Ubuntu and prepared this short (and totally new) test file.

1. File->New->Presentation
2. Click subtitle area (Default first slide is a title slide)
3. Enter text and press Esc so that focus is on the area not on the text
4. Right click on the focus border and choose Area
5. Choose some fill color.
6. Change tab to Transparency.
7. Choose Gradient radio buton
8. Choose Radial, Ellipsoid, Quadratic or Square Type - all affected.
9. Change Center X and/or Center Y to something different than 50%
10. <ok>, f5

BTW. On the preview of next slide in the slide show it all appears ok.

[Reproducible] (with own documents and reporter's sample) with "LibreOffice 3.4.4  - WIN7 Home Premium (64bit) German UI [OOO340m1 (Build:402)]", also
[Reproducible] with Server installation of Master "LibO-dev 3.5.0 – WIN7 Home Premium (64bit) ENGLISH UI [(Build ID:  4f11d0a-adcf6d5-c4bb9bd)]" Windows_2008R2 - 111118).

Center in presentation mode always is 50%/50%, different settings for shapes or text boxes will be ignored.
Worked fine with "LibreOffice Portable 3.3.3  - WIN7  Home Premium (64bit) German UI [OOO330m19 (Build:301  Tag]", so REGRESSION

Might be related to "Bug 42553 - VIEWING: wrong gradient geometry in Presentation mode", but that one started with 3.3.0

I tested with master, 3.6 and 3.5 sources, 3 updated today.
master: it works (there's a crash during closing but that's another bug)
3.6 and 3.5: impossible to confirm or not, LO seems to enter in an infinite loop and I got this log repeated ad libitum:
 warn:legacy.tools:20042:1:/home/julien/compile-libreoffice/libo_3_6/solver/unxlngx6/inc/vcl/salbtype.hxx:420: Pixel represents color values!

Rainer: should it be considered as RESOLVED/FIXED and perhaps file a new bug? or do you think otherwise?

Tested again with WIN
LibO 3.4.5: reproducible
LibO 3.5.1: geometry problem solved (but color much to bright)
LibO geometry problem solved (but color much to bright)
LibO geometry problem solved
LibO geometry problem solved
LibO geometry problem solved

WFM as suggested.
