Description: In a Presentation a Fad-In effect is used. This appears very clumsy because the Duration setting does not seem to be taken into account properly. The fade-In appears to last randomly long and a sequence of multiple animations looks quite clumsy. Steps to Reproduce: 1. Open provided Testcase in LO 2. Change to presentation mode 3. Second slide is using "Appear" Effect instead of "Fade-In" with appears much smoother. Actual Results: Animation is stuck and looks clumsy Expected Results: Should be closer to Slide 2 Reproducible: Always User Profile Reset: No Additional Info: The document was originally made in MS PowerPoint.

Created attachment 202706 [details] video with cpu spikes Confirm. As per my attachment, we can see cpu spikes during the times when the presentation freezes. During these times, we can also see the timer to be stuck. There are 2 freezes : one before showing the number 1 during 3 seconds, the second before showing the number 4 during 5 seconds.
