Character state change flashes

I have been wrestling with a similar issue. Character Connie and Hazel jump when moving between states. The character visibly moves to the right a few pixels then back again to original location with the new state. I do notice it in preview and in articulate review. So, not sure if the browser is relevant.

 It is only when the pose of the character changes, not the expression of the character. So, say the arms are down and you change it to hands on hips...the whole character does a little dance to the right and back to move the arms.

Creating a new slide and copying over the objects does not fix it.

Re inserting the character and recreating the triggers does not fix it.

Changing the character does not fix it.

Steps to recreate (and show when it isn't an issue) in a new project

1) blank slide insert a classic character

2) create a trigger and change the state of character to 'asking' when timeline reaches 1 sec

3) at this point...preview the slide. No jumping.

4) go back to edit mode, add a shape to the slide at the beginning of the timeline

5) preview the slide again....here is where I start to see jumping

6) change the trigger to move the character to 'thinking' instead of 'asking'

7) preview the slide. Jumping.

Play around with it. There seems to be some magic combination of shape, timeline, pose, and trigger timing that causes the jumping to occur.  Like, if the shape appears on the timeline at the 1sec mark then I don't get the jumping. If it is a smidge before OR after the 1sec mark, I get jumping. Asking pose seems to be more sensitive than thinking pose. Modern characters jump even without any other shapes on the slide.
