Smart animate stretches vector shape?

Hi, Im testing out smart animate in Figma and I am used to auto animate in Adobe XD. Im trying to make a simple animation, but have a problem with smart animate. You can see really bad pixelation, which is weird because Figma is using vectors… :thinking:

Does anyone know why this happens?

Here is a link to the demonstration: Figma smart animate - YouTube

Thanks for the help!
