White background on .mx_BaseAvatar_image makes dark profile pictures look terrible on dark theme

[Qwertie-]

When you have a profile picture with a black edge it gets a very thin white border around the image which looks quite bad against the black background of riot.

I assume this is here to make images with transparency visible on all background colors but I would argue that having no default background lets those groups set an icon with a proper background color where as the current setup makes it impossible to have a good looking icon on dark themes.

The background color really should not be visible on the edges of an image with no transparency though.

The image in #3203 seems to show the halo in the typing-notification-avatar rather than the inline-with-message-text avatar, so these can stay separate for now (though I expect they are closely linked and would be dealt with simultaneously).

This also affects transparent avatars. Relayed from #riot (starting at https://matrix.to/#/!DgvjtOljKujDBrxyHk:matrix.org/$15041096531463006EUJlK:matrix.org)

there is a white bg behind my profile picture for some reason, which kind of defeats the point of supporting transparency in profile pictures
if someoen thinks their icon might look bad with transparency enabled they schouldnt enable it :/

Their avatar in question is 100% transparent: https://t2l.io/_matrix/media/v1/thumbnail/matrix.org/KmaJJyCiQMOqIBYSqebjYFzG?width=30&height=30&method=crop

Closing as both the dark and transparent cases have been fixed for some time
