Coworking as in you're the only trader at the office space...I couldn't tolerate others from the space seeing my screens especially if its a "visitor" of someone else that's renting a space there.
In contrast, coworking as in you're among other traders doing the same in the office...someone looking at your screens "may" be ok but only if they asked for permission. Yet, if they're just walking by and they happen to take a quick look at your screens without disturbing/distracting you...its ok.
Yet, may work if you have one of those corner desks that nobody can walk up from behind you.
I myself get annoyed when my kids enter the office and slowly walk by while looking over my shoulder...looking at the screens especially when they are eating something (loudly).
