Created attachment 467909 [details] Missing COLR support As shown by https://pixelambacht.nl/chromacheck/ in https://github.com/Fyrd/caniuse/issues/1018#issuecomment-1737111439 Safari 16 supported COLR (v0) but Safari 17 does not. This causes emoji in the Twemoji COLR font on app.element.io to render entirely blank for example. Switching to SBIX works as a workaround as can be seen on develop.element.io
