IntelliJ Editors just straight up not working on Wayland right now has driven me insane. I really like Sway (i3) and Wayland is a must for mixed DPI setups. Now I have started using Kakoune and LSP for Go and Python and it works great. I tried Neovim for a while but having another window manager inside of Sway is too much of a burden. Kakoune opens new windows in Sway (or tmux). Combined with a plugin to make Firefox open tabs in a new window always I found my dream setup.
