Create a new presentation with only a bit text on a side. Then add the custom animation credits (Abspann in German)to the text. You will see a black rectangle during the preview inside the menu bar at the top of LibreOffice. Environment: openSUSE 11.4-x64, KDE 4.6, Nvidia-Graphic-Card Geforce 9600M GS (Laptop), Intel Core2 Duo 2 Ghz).
@ Rainer Bielefeld: I tried this custom animation with your sample document from Bug 35278.
Created attachment 49849 [details] A screenshot of the rewrite bug at the end. This is the screenshot after the preview was running. The black rectangle was a bit bigger beforehand.
@ Rainer Bielefeld: could you please test it with Windows?
@Andreas: Might be a "DUP of Bug 35278 - VIEWING: Custom animation ends with filled rectangle". I will check the Details tomorrow.
Reproduced on LibreOffice 3.4 340m1(Build:103) for OpenSuse Linux. Problem occurs exactly as reporter describes. The custom animation name in English is "Move Credits". It is under "Exciting" in the "Entrance Tab".
DUP of "Bug 35278 - VIEWING: Custom animation ends with filled rectangle", what already has been assigned. @reporter: Please feel free to reopen this Bug if you find evidence that we have an independent issue here. *** This bug has been marked as a duplicate of bug 35278 ***
