Hello, Confirmed with firefox 130 on sid. The suggested workaround to disable AVIF support works, images are correctly rendered after a reload. For reference, the setting is image.avif.enabled.
I'm wondering if the underlying issue in libyuv could also be the cause of another bug I'm experiencing, where my webcam video in google meet is correctly rendered for me, but other meet participants receive my stream with garbled colors. No idea how to work around this though. Best regards, -- Julien Leproust
