The rendering of the text effect on the 1st slide of the document from bug 78267 (InfoBenutzerdefinierteAnimation.odp) has changed in master - the first part where the color of the letters change disappeared.
No idea what is the desired effect there, but looks like a regression; so I'll revert the offending commit.
