DBus activated services such as mako use the XCURSOR_THEME and
XCURSOR_SIZE environment variables to decide how to show the cursor,
so without these, the cursor may not match the rest of the desktop
when hovering over (in this example) mako notification surfaces.

The default config for sway generates a bar block with tray_output primary. But wayland (or sway, take your pick?) has no concept of a primary display so this just results in no tray anywhere.
A better default is "*" which puts the tray on every monitor, since sway can do so without issue.
