Yeah, it's pretty weird! It's definitely not the case with these versions of OSD running on their own... This "switch" isn't something that happens normally between these versions, so there...

It's definitely in the tile images. For example: https://static.historiska.se/iiif?IIIF=KMK_DIG56213.iiif.tif/0,4096,2048,575/256,/0/default.jpg It's not in every tile at every level; you can see it coming and going as you zoom in and out....

Indeed, this is a known issue: https://github.com/openseadragon/openseadragon/issues/1614 Evidently no one has decided to take it on. Let me know if you are interested in working on it and I can...

@pearcetm Cool! You should add it to the plugins list. Here's the file to make a PR against: https://github.com/openseadragon/site-build/blob/bec487a0223f37eba848c945df8adf0d1941cf3e/www/index.html#L168 Maybe it would be good to start a new section in...

Oh, sorry... Looks like I gave you the wrong information... It's `OpenSeadragon.setImageFormatsSupported`, not `viewer.setImageFormatsSupported`. Can you get access to the base OpenSeadragon from Mirador? You shouldn't have to modify the...

> Not that I know of, in Mirador, viewer is the instance of OSD. We don't want an instance of OSD, we want the OSD static namespace. Have you tried...

I've filed https://github.com/openseadragon/openseadragon/issues/2454 for adding webp support.
