Description
Stickers sometimes have a non-transparent background (using https://github.com/maunium/stickerpicker) I asked the stickerpicker dev about it and they told me it was most likely dendrite.
Steps to reproduce
- Create a stickerpicker instance and implement in element
- Send stickers, most of them will have a black background, but some will have a transparent background
What is expected is that the background would be transparent.
(Maybe it would help to add the MXC URLs to those three stickers there, to be able to inspect them)

MXC? Do you mean the link to the image file?

Yes, i'll thumbnail these via dendrite.matrix.org, since it seems to have the same issue. Curiously enough, these images also dont scale properly (as is instructed via the query parameter)

identify and file dont find anything weird with these.
jboi.nl (a synapse server, my own) seems to find no issue with these:

matrix.org seems to have these wrong cached, by the way, giving a larger image than needed.
I'm planning on changing the webserver I host these on, will that cause any issues with the images you posted?

also those synapse images appear to be very small, I like the current size of the stickers (they aren't emojis)
Synapse is displaying the thumbnail sizes correctly, scaling it to 128, its matrix.org that has this cached incorrectly.

I'm not referencing your server domain for privacy concerns, but unless you also change the domain (which has its own can of worms), everything should be alright.

I am going to change the domain lol (where the stickers are hosted)

That's not going to fix the problem, to dendrite, they'd be the same files, regardless if they're hosted on other servers, or the same one.
