Yes I use Xenodm. Someone (developer I believe) on reddit suggested that it was more secure to run X as user that way. I was tracking current (having only recently switched over to that from stable), but a late upgrade had no chromium available on the mirror I use so I reverted to 6.4 release.
The image was captured by running a tmux in X, more usually I run that on the console so the dotted lines return anyway (using TERM=pccon0 keeps the colours and seems to work well IME). Works great when you ssh into that box and tmux attach to its session. (I know you know all this but for the benefit of others) Any old low powered device - provided it can run ssh then has access to all of the tmux windows/functions. Nice for collaboration also as you both can control/see the exact same things when actions/changes are made.
