Color emojis fail to render OOTB on Ubuntu 24.04 LTS #87

Closed alexmurray closed 4 months ago

alexmurray commented 4 months ago

Color emojis work as expected on Ubuntu 22.04 LTS but fail on 24.04 LTS - this is tested by just running:

emacs -q

Then switching to the scratch buffer and trying to insert an emoji via C-x 8 e e and noticing that the emojis offered by the minibuffer are all black and white, not color.

A quick test of removing the export of our local FONTCONFIG_FILE at https://github.com/alexmurray/emacs-snap/blob/ac89b1141a261b40ab5607f8d74209ede4c164cc/setup-env#L31 does nothing to help fix this. This needs more investigation.

This appears to be an issue in Ubuntu 24.04 LTS itself https://bugs.launchpad.net/ubuntu/+source/fonts-noto-color-emoji/+bug/2054924

Closing this as it is not an issue with the emacs snap itself.
