Avatars with transparent background are shown with the avatar circle being either white (or transparent, but likely doesn鈥檛 look good in dark mode) so that the logos / icons are shown correctly.
The randomly generated color from the avatar placeholder shows through in the background. This happens for quite a lot of mails:

Shown are e.g. Meetup.com, Mattermost, FSFE, Open Source Initiative, Tito, Pretix, Eventbrite and Twitter.

I wonder if this is coming from the nc-vue lib or our code. We actually show either the placeholder or the image: https://github.com/nextcloud/mail/blob/374ad54ea0c1956d77b032817111b3a0af10e1cc/src/components/Avatar.vue#L23-L24
@skjnldsv @juliushaertl @nextcloud/vue can you shed light on that? ^
Not sure if that is set somewhere, but I also cannot reproduce
@juliushaertl on mail Jan showed it to me. :man_shrugging:
Can鈥檛 reproduce it on cloud.nextcloud.com either so if you can鈥檛 reproduce it on your local installs, I guess it might be some misconfiguration of my dev instance. :)
Can reproduce it again, on cloud.nc, also same issue as in Contacts at https://github.com/nextcloud/contacts/issues/1066
