At distance >= 20, v0.6.1 + kimageformats + Gwenview fail to properly render nightly's output

[antermin]

Describe the bug

When I use nightly cjxl to encode an image at a high distance (>=20), and uses Gwenview to view the output, the output is corrupted.

To Reproduce

1. Encode an image with nightly cjxl: cjxl -d 20 wollerau.png new-20.jxl
2. View the image in Gwenview

Expected behavior

The image should be rendered properly without any glitch.

Environment

• OS: Arch Linux x86_64
• Libraries:
  • cjxl v0.8.0 c76ec204(nightly CI build)
  • djxl 0.6.1 (Arch package)
  • kimageformats 5.97.0 (for JXL Qt plugin)
  • Gwenview 22.08.0
• Test files

It might be a bug with djxl 0.6.1 since I just tried manually decoding it both with djxl 0.6.1 and djxl 0.8.0 Git from 2022-09-06, and only djxl 0.6.1 returned a similar error.

I can reproduce this issue quite easily on my end as well at a system level.

Interesting that the problem with new-20.jxl manifests when getting the buffer as 8bit integers. When reading as 32bit float, whole image is displayed.

But I have another distance 20 file:
gimp299_plugin_crash.zip

It is triggering following assert in GIMP 2.99.11 (uses libjxl 0.6.1 from MSYS2):

In case of GIMP, there is not a big problem, because only plug-in process crashes.

But in case of KDE/Qt applications, whole application is terminated.

So we are waiting for libjxl 0.7.0 release.

So, I guess this can be closed with the coming 0.7.0 release.

Closing, because this is fixed in the 0.7.0 release
