The first frame of particle animation probably goes wrong. It should be a little circle rather 'an an already boomed one.

At about 2'33", when the Warden is attacking a Zombie above.
The first comment below this video as well pointed out,
"I sus that programmers perhaps reversed the first frame and the 15th frame of Sonic Boom, resulting less smooth of the dynamic sense."
I've forward-resolved this towards MC-250662, since that bug report has more information/screenshots in it and doesn't require watching a video to fully understand the issue.
What is the time in the video when the issue occurs?
