Description Sarper Akdemir (allotropia) 2020-08-30 17:39:26 UTC
Description:
When there is two or more parallel physics animation effects going on, and they have different durations. When one of the animaton effect ends there is a jump in the other animation effects.

Steps to Reproduce:
1.Add two shapes with Fall Simulated
2.Set first one a duration of 3 and the second one a duration of 5
3.Make second one start with previous
4.Play the slide

Actual Results:
When the first animation effect ends, there's a sudden jump in the animation

Expected Results:
When the first animation effect ends, there shouldn't be jump and the animation should just keep going.


Reproducible: Always
