the icons want to stay incognito :)

but yes, this is a longer standing issue ... fixing it was always superseeded by more important things :)

also sending/pending icon is different to the other platforms and lacks the animation. maybe that is easy enough to fix at the same time.

[Simon-Laux]

maybe we could use vector icons instead?

nb: it is okay in the chatlist, it is blurry only on the message list.

the issue probably is the NSTextAttachment, cmp https://stackoverflow.com/questions/27281945/blurry-image-nstextattachment-on-nsattributedstring , svg does not help (tested with SFSymbol images)

we should either not use NSTextAttachment or apply a fix as described on stackoverflow above

Only for the padlock icon though in my tests, the other icons were fixable without using svg in #1921

[r10s]

maybe #1921 is indeed good enough, i will have a closer look when 1.42 is out and resurrect as needed. the svg needs to be removed, the png are not the issue in general,

maybe a horizontal stackview is the prober solution, this NSTextAttachment is blurry even for svg of #1921 (although already far better)

the svg are not that share as they could be; still an improvement, though
