It looks like the animation has noticeable breaks between line segments, is that fixable using line_fraction in the fragment shader to make the segments agree on dot/dash positions?
I've also noticed this already back in the day when I was still working on the last two attempts at this PR. This has nothing to do with the animation. It is a fundamental issue with the shader used to render the gizmos and the more complex gizmo shape methods.
Currently most of the gizmo render methods are based on the line method as a fundamental building block. So line strings are basically just a bunch of lines unaware of each other. This is also reflected in the shader code which always just draws a single line and makes no connection between them.
I will spin an issue out of this comment so we have a better place to discuss this.

It is especially visible with the animated gizmos from the linked issue
