Created attachment 135591 [details]
Open the attached PPTX (created by PowerPoint) with Impress, and save it again as PPTX.
The fade out animation is shown correctly as the file is opened for the first time.
Upon reopen and playing the slideshow, however, the shape fades in instead of out (but disappears at the end, just the fade animation is wrong). Same when played in PowerPoint.
