It looks like there are only two big bugs keeping it from running in Wine, etc., a flickering issue and the fact that they're using a deprecated Windows API call to save to disk. However, they also seem to show no interest in making it work. They'll still have to update that call eventually, though.

They really should fix it. The fact that they're selling software and not subscriptions (unlike the competition) means that if they get one version running well on Wine, they could take as long as they wanted to get any later version running. Linux users will just be a year or two behind everyone else, but they'd be grateful.

Supposedly they're a relatively small team. According to another comment (I don't use it personally), they're missing a lot of features Adobe has had for decades, so they would probably understandably prioritize porting to Linux under even that.

Same here. I'll gladly pay for Affinity on Linux.
