I collected some mastodon links so you know roughly what to look for:

• here’s a game developer unable to do window positioning, multi-monitor, display type detection, hi-DPI… in portable ways on Wayland. window positioning in particular bites game developers hard, and is still unfixed for, gonna be honest, horseshit security reasons.
• this entire thread is kind of an excellent summary
• screen recording on Wayland sucks, and what’s interesting about that thread is the smug person replying gets it (to my memory) wrong, portals for screen recording are a hack
• in fact here’s the post where Ariadne told me I was wrong about portals; it’s also a good starting point if you want to see what protocol discussions look like
• here’s one of the jwz threads out of many

in conclusion: how dare I. don’t I know these are just poor, mostly corporate-backed volunteers
