OBSERVED RESULT Some JPEG XL images opened in applications like Gwenview, Okular, and Nomacs, anything that relies on Kimageformats, JPEG XL shows up stretched. It's like the image is rotated slightly to the right with a melt effect from top to bottom. EXPECTED RESULT Images should show normally Operating System: ArcoLinux KDE Plasma Version: 6.2.3 KDE Frameworks Version: 6.8.0 Qt Version: 6.8.0 ADDITIONAL INFORMATION
Extra info: This is def a new issue because previously, on older versions of Kimageformats, in the mentioned applications, the images always showed normally; it's only as of late this started happening, and this only affects Kimageformats-reliant applications; any other image viewer that doesn't rely on Kimageformats shows the images properly.
You wrote "some JPEG XL images", please attach an image showing the problem.
Created attachment 175943 [details] Jxl distortion As you can see here, Gwenview, Nomacs, Okular, and an application called Manga Reader all show the image distorted. Also, this only seems to happen on very specific grayscaled images. Also, if I downgrade to kimageformats version 6.7.0 from 6.8.0, these distortions go away.

I'm not saying I don't believe you, just that I need the JXL file that is distorted to fix the plugin issue. Can you attach the offending JXL file here?
Created attachment 175949 [details] This image Alright here's the image.
OK, it's a Gray+Alpha image. The bug was already fixed by MR !267 (https://invent.kde.org/frameworks/kimageformats/-/merge_requests/267) and will be included in KDE Frameworks Version: 6.9.0.
