Screen sharing on Discord with Wayland kinda sucks at the moment, but I believe that's moreso Discord's fault for not updating Electron or something along those lines.
If you really need screenshare there were some options with xwaylandvideobridge, a custom client, or just running it via the browser
why even install multiple copies of chromium in the first place if all this electron proprietary garbage comes with virtually no extra features compared to the web version, in the first place?
If you use scaling some apps can be blurry. Oh and screen sharing doesn't work on discord cause they refuse to update their app. Other than that it was smooth sailing for me
Both teamviewer and rustdesk are acting funny as hell since the upgrade. Seriously buggy for me. Screen locks up. Keyboard and mouse also act funny. tiger vnc is ok at the moment. That’s my biggest takeaway. It’s been hard to do stuff remotely with Wayland enabled.
Afaict wine uses XWayland. Sometimes with my games I'll have problems like the game running on one display and expecting input from the other, even when I've switched the second display off with wlr-randr. I also have occasional UI scaling problems. Most things works well most of the time though.
With a good compositor, Wayland itself is probably ready enough for most cases. A lot of applications need to be updated to better support it though., and that seems like a lot of work.
