[Message part 1 (text/plain, inline)]

Hi,

I just rebuilt Emacs master with nativecomp+pgtk+imagemagick and can confirm the issue is still present.

I tested with full Doom-emacs config, a minimal from-scratch config as well as ’wmacs -Q’ and issue is present on all 3.

Testing older Emacs version will be bit challenging for now, but I will see what I can do over coming week.

Also about the images being WebP/AVIF, I see an explicit image tag with `jpeg' file as src, can eww not prioritise that?
I disctinctly remember Emacs/EWW was able to show this in the past, but I cannot recall what version and library support that was.

I have tried doing this as well, but hasn’t worked for me yet. ’convert’ is present in PATH and Emacs variable is set but doesn’t seem to be working yet.
I will debug more when possible.

I know as much C as my cat, but I can help with testing and debugging if anyone else with the knowhow is willing to put in the time and work.

Thanks,
