Sway can't set my 3 displays as extended like I can with i3 with xorg.
Also I recently wanted to try to record on OBS with sway to rule out an issue that I have with my AMD card with colors, and I wasn't able to get OBS to work, installed xdg-desktop-portal-wlr, set the XDG_CURRENT_DESKTOP=sway environment variable and didn't work.
Also for some reason my xfce4 apps are ignoring my xdg base dir variables (I have config and cache inside ~/.local) when using either sway or hyprland and that results in issues with my theming and the creation of the .config and .cache dirs in home again, what is weird is that it only happens with the xfce apps.
EDIT: I was able to test OBS on hyprland instead of sway and the issue with the colors is still present even on wayland.
