Green overlay on images with AVIF format

[iroyo]

Describe the bug Green line (vertical or horizontal) in some images when using AVIF format (above 31). Example of "Accept" header used: "image/avif,image/webp,image/apng,image/svg+xml,image/*,*/*"

To Reproduce Sample project here coiling-avif Steps:

• Open app in specificed device
• Click the button LoadImages
• Green overlay line appears

Example of cURL (we can output that into an image to see the visual artifact is NOT present)

curl 'https://shop.mango.com/assets/rcs/pics/static/T7/fotos/S/77004767_40_D7.jpg?ts=1722591772050&imdensity=1&imwidth=538' \
  -H 'accept: image/avif,image/webp,image/apng,image/svg+xml,image/*,*/*' \
  -H 'accept-encoding: gzip' \
  -H 'connection: Keep-Alive' \
  -H 'host: shop.mango.com' \

@iroyo Thanks for the repro project. Does this still occur if you update to Coil 3.0.0-alpha09? It updates to use the new ImageDecoder API. If it still occurs does it occur if you decode the image directly with ImageDecoder?

[iroyo]

Hey Colin thanks for the fast response,

Sadly, after bumping up the coil version I still experience this visual artifact in the image when using AVIF I have updated the repo linked above

Let me know if there anything that I could try, or something that I could investigate

[colinrtwhite]

@iroyo if you decode the image directly with ImageDecoder (no Coil) does it also show the green line?

[iroyo]

Sadly, I think I've come to a dead end... ImageDecoder versions seem to have the same issue.. this implies its an Android problem right? ¿ Because I see no green line when I open the file in my computer

[colinrtwhite]

Yep unfortunately this is likely an Android platform issue. Can you file an issue with the Android graphics team please? If they say there's a reasonable work-around to add to Coil we can do that.

Closing as this is a platform issue with Android's decoders please file an issue with the graphics team.
