jxl problems

[JackDropHammer]

Describe the bug
So, it seems like the jxl decoder is brokern, not the encoder but the decoder. If you convert an image to jxl (lossy/lossless) it comes out correct(checked by using a browser) but the preview is simply incorrect (horrible quality with tons of artifact).
If you try viewing the image in the app the same problem occurs. Comparison here;

It doesn't end there because if you convert from jxl to any other format, the image will look the same as in preview. So the image will become horrible.

This same problem seems to present in avif. (full size image :- https://postimg.cc/5jzsHR0Z)

EDIT:- I haven't tested any of this in programs like imagemagick(sorry)

Can reproduce with jxl on version 2.7.1-beta01-foss(128). Images are encoded properly but decoding shows wrong colors, the quality is the same, converting jxl image (from ImageToolbox / jxl-coder) to png does not show the wrongly decoded result

Cannot reproduce with avif

What version are you on?

[T8RIN]

Maybe it's fixed in jxl coder 2.1.6

I'll close for now, wainting for updates

[kremzli]

i think this is the fix https://github.com/awxkee/jxl-coder/releases/tag/2.1.8

[T8RIN]

Maybe, btw i updated to this version now

[kremzli]

my first comment is still happening (with 2.7.1 beta 2)

[T8RIN]

Anyways that's not handled by me

[kremzli]

Cannot reproduce outside of ImageToolbox awxkee/jxl-coder#16

I don't quite have the color issue, but the preview in "compare" (on the right siide of the slider) shows what looks like a noticeably lower resolution version with tons of aliasing. I just started using the app, so I can't compare it to before previous fixes to this issue to see if it's the same. I don't want to necro if it's not necessary.
