How to avoid the "jump" in the middle of my morph?

Hello. I'm a new user of Morpheus.
I've created a simple morph of some text, from one font to another. The background is fully transparent. I used lots of "dots" to try and make the morph smooth. Only one color is used (the same for both images).
I've saved it as an Animated GIF (hoping to preserve the transparent background; I'm not sure if that's the best way to do it or not).
Unfortunately, I get a weird "jump" and some flashing in the middle of the morph. How can I avoid that?
Thanks for you help.
Here's a link to the GIF (I have the raw files too if that would help you).
