“Jumping” is caused by slight differences in the position of similar items on consecutive slides. When you flick through your presentation quickly, it looks like these items “dither” (like in a cartoon). Try to avoid it for a calmer presentation. Jumping often happens in:
- Slide titles
- Vertical (y) axes of data charts
- Animation buildups spread over multiple slides
To avoid it:
- Use the drawing guides
- Control-C an object on 1 page and copy it using control-V on the next to create the exact same position
- In the worst case use size-position to set the exact coordinates of an item
