+# FIXME 2024-03-26: Screen sharing on sway is a pain to set up because
+# apparently the XDG_CURRENT_DESKTOP is not set by default and so the
+# `xdg-desktop-portal-wlr` does not work. I had other issues as well,
+# where Emacs does not read the environment variables specified by
+# environment.d. This is an issue I do not have on GNOME's Wayland
+# session. Of course, I can change the .desktop file or revise how I
+# start Sweay but I am not a fan of such workarounds: this should work
+# out-of-the-box. Back to Xorg or GNOME, I guess...
