Hello there, dear traveler! Welcome to the Hyprland Wiki!
Take a tour of the pages on the left and read ones that you may need.
A Wayland compositor is a fully autonomous Display Server, like Xorg itself. It is not possible to mix’n’match Wayland compositors like you could on Xorg with window managers and compositors. It is also not entirely possible, nor recommended, to try and use all Xorg applications on Wayland. See this page for a list of recommended Wayland native/compatible programs.
Wayland compositors should not be confused with Xorg window managers.
GTK apps launching slowly and/or OBS/Screensharing not working is easily fixable by checking out the FAQ (GTK issue) and FAQ (screensharing).
If you are having issues, please try reading the FAQ and configuring sections — chances are your issue is described somewhere there. If not, you can try searching the issues or joining the Discord server.
