Every once in a while plasmashell shell seems to go a bit bonkers. I will lose the
background image on one or both of my displays. Also the systray will lose its
transparency. When this happens I simply kill/restart plasmashell from the command line.
Doing so results in restoring things but a bunch of output with warnings/errors. Among
them are....

It seems most people that say they are "done talking about it" never really are
until given the last word.
