Reported also in and found out problem in gwenview https://github.com/caco3/kim5/issues/14
I cannot reproduce this on Gwenview 25.08.1. Anyway, this would be either a bug in imagemagick that KIM uses internallynot in KIM itself. (not sure about gwenview, but there I assume some underlying libraries are also being used). I am closing this then, if you can reproduce it on a recent Ubuntu version, please reopen.
