@fz0000 commented on GitHub (Nov 15, 2025):

This is a feature, not a bug.

Gifski optimizes GIFs by merging identical frames: if the frames are visually identical, it will merge them into a single frame with a longer duration. This is a core feature to make files smaller.

To avoid it, you can try to make each frame slightly different, e.g. add a tiny amount of noise to every frame.

If you wish Gifski had an option for completely frame-by-frame output, you can submit a feature quest on Gifski's repo.
