Responsible commit?

negativo17/libheif@4a4cbd9

affected hardware: possibly everything that uses i915?
Pentium B940 SandyBridge = Gen6 Graphics called just "HD Graphics"
Celeron G1840 Haswell = Gen7.5 Graphics called just "HD Graphics"
Celeron N4020 GeminiLake = Gen9, UHD Graphics 600

Not an issue on amd, also not an issue on newer intel graphics like Intel Framework 13th Gen.
I tested with a fresh installation of bazzite on a flash drive. This should not be a config issue.

Possible Workaround

sudo rpm-ostree override replace --experimental --from repo="fedora" libheif heif-pixbuf-loader

the vanilla fedora packages are not broken in this case, they still ship an old version.

I have not tested if the "less crippled" version from negativo is responsible because it is a newer version or because it has more codec support.

I couldn't figure out how to build the negativo rpm from master branch. So I don't know if the new version would fix anything.
I'll happily rebase to some testing image/layer some rpm.

I have not tested if the "less crippled" version from negativo is responsible because it is a newer version or because it has more codec support.

Grabbing the crippled 1.19 rpms from fedora 42 makes it work.
https://src.fedoraproject.org/rpms/libheif

sudo rpm-ostree reset
sudo rpm-ostree override replace "https://kojipkgs.fedoraproject.org//packages/libheif/1.19.5/1.fc42/x86_64/heif-pixbuf-loader-1.19.5-1.fc42.x86_64.rpm" "https://kojipkgs.fedoraproject.org//packages/libheif/1.19.5/1.fc42/x86_64/libheif-1.19.5-1.fc42.x86_64.rpm"

Maybe the library will get updated anyway in the next few days and negativo just catches up and we don't have to do anything.
