Yes to both.

Nothing changes with the system tray icons when I toggle the desktop effects

This is strange, restarting plasma-desktop does remove the icon but it
leaves a blank space in the system tray where the icon was located.
Which makes for a really awful looking system tray.

The systray config options treat the "phantom" icons as expected.  It
will hide the icon when asked, and it is show when 'show hidden icons'

Once I have quit the application, the process does disappear from the
process list.
