Example screenshot, which can't be opened with gwenview.
SUMMARY
Opening some (not all) old screenshots of various resolution (converted to .jxl
in q4 2023) results in "Loading image failed." message.
Those screenshots that fail to open in gwenview, are able to be displayed
properly in ristretto.
STEPS TO REPRODUCE
1. Aquire .jxl file lossly converted with imagemagick (version possibly from
2023-10 to 2023-12), and later possibly modified with "file optimizer" software
2. Observe that the file has a proper thumbnail in dolphin
3. Open said file
4. Observe result
OBSERVED RESULT
Gwenview opens, but instead of showing the screenshot it shows
"Loading 'Zrzut ekranu 2023-02-7 o 12.03.33.jxl' failed
Loading image failed."
EXPECTED RESULT
Gwenview opens, and shows the screenshot.
