Did you try the latest nightly build to see if the problem got fixed?

Yes, and I updated the debug information above (yazi --debug) to the nightly that I tried

Describe the bug

The image previewer for Kitty is displaying weird artefacts on transparent PNG images like shown:

This is how it should look like:

Minimal reproducer

Preview these images in Yazi:

You will find that all of them have weird artefacts.

Anything else?

Joshuto seems to preview these images just fine, as shown:

Joshuto uses ratatui-image to do its image previews, so maybe following what ratatui-image does would work.

Version: 0.3.3 (Arch Linux 2024-09-05)

Yazi has supported transparent images only since PR #1556. Currently, you need to use the nightly version.

Also make sure to do a yazi --clear-cache after upgrading to the latest version

[hankertrix]

Ah I see, I forgot to do yazi --clear-cache after running the latest master version.

Sorry for the noise.
