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

This is on current Firefox stable on standard 1920x* display browsing https://hub.disroot.org/pubstream

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)
