It's up to the new HEIF library which broke other packages including GM, GIMP, etc. See the relevant bug report in Debian [1]. Its upstream stated to solve this, but it seems not the case [2]. That's why GM and others can't use the mentioned display formats. Regards, Laszlo/GCS [1] https://bugs.debian.org/1041242 [2] https://github.com/strukturag/libheif/issues/974
