Hi Phillip,
this seems as an issue/misunderstanding about where a new container
appears.
Basically, the grey lines indicate nested stacked containers,
and they try to indicate that with the label: `S[S[S[x y z]]]`
indicates that that line belong to a stacked container that holds
*single* child container `S[S[x y z]]` (note one less `S[]`).
The last grey line (`S[x y z]`) is the actual stacked container that
holds all your stuff (`x y z`).
You should be able to get rid of these by focusing the inner-most
stacking container and try to move it around; that usually works for me.
I do not have a sufficient understanding of the container tree
manipulation to advice any further, but maybe the i3 docs
on this topic [1] could shed some further light on it.

Hope this helps!
