recently i found out that gimp supports avif formats nicely but downloadfrom fedora repo as rpm or flatpak does not comes with avif support but as I recall, AVIF has been created on purpose not to make any legal issues. Though I’m not a lawyer of course
can anyone look into as gimp downloaded from flathub or snap works normally.
i now understand the issue with fedora packages gimp uses libheif for avif images but heif is a conflict of license due to apple so unless gimp have a better support for avif(av1) unlike plugin that gimp is using rt now. this package issue will be resolved but i think using flathub package will resolve that and also as fedora making default to flathub. it will resolve for flatpak.
no i have not install libheif or libavif i find the issue as installing with apt on ubuntu works but in fedora installing from dnf does not work
It certainly should work if you have the correct rpmfusion repo enabled.

yes exactly what happened now i have installed it from flathub and does not any issues followed by that but something strange happened that just on a clean vm of ubuntu 23.04 and fedora 37 i find avif files show thumbnail in ubuntu but that is not the case in fedora is it the same reason.
