Lines flickering off and on when "asset warp" tweening

Is there any other solution than converting to fills? I used a specific brush for the lines so I can't convert them to fills.

Convert the strokes to fills. It happens because of the stroke deformation during tweening.

I have the same problem. can you tell me how did you solved it, please?

I have experienced the same thing quite often lately due to a project where the vectors are rather complicated and close together. I find often if the asset warp tween works by NOT breaking the vectors, adding an ease will break the vectors. Optimizing can help but it is not a solution most of the time. My only work around is to not use asset warping or after tweening an asset warp, convert to keyframes and manually go back in and fix. Not the best answer I know. The shape tweening engine needs some tweaking. It's getting much better but it's often how finicky vectors can be.

Am still trying to figure this problem out and, even after the update, no matter what I do fails to fix the problem.

Since initially posting this question, I've tried the following things:
-Converted the lines to fills by using Illustrator's "outline stroke" feature.
-In animate: have tried multiple ways of breaking things apart, grouping and simplifying.
-importing it as an SVG

None of these seem to be doing the trick.  I was trying to keep the image a vector but, if this continues, I'm just going to import it as a png, file size be damned.
