pubstream - posts on right hand side display 1 character per line [DisHub]

This is on current Firefox stable on standard 1920x* display browsing

yes. this is known issue with beetroot theme. For now you could just switch to redbasic.
Since hubzilla is sort of back online and sort of stable for over a week, I am planning to work on redoing the entire theme, starting from small fixes like the pub stream. So this should be solved soon (unless i get sucked into some issues that need priority)
