Gif to WebP causes slow frames

[mpeyfuss]

Encoding a gif to webp causes a weird lag/stutter. I've noticed it only on a few gifs. Most of the time gifs to webp works just fine. What about this gif causes issues?

Here is are links you can try out:

Which browser was this tested on? I noticed it causes some lag and stutter in Chrome, but it displays fine in Firefox.

I tested in Brave (chromium). Firefox works great. Safari is even worse than Chromium engine.
