I started using Pop OS distro for a week now and i wanted to play SS13 but i'm having issues.
I used this tutorial(link below) and it actually worked, i can open BYOND and join a game, but that's as far as it goes. I can't access most machines, the test can only be read without the "fancy one" also text doesn't appear above the characters and many other annoying UI problems.

Is there any way to fix?
If not, is there another tutorial i could use so it works properly?

Link for the tutorial i used: a_stepbystep_guide_on_running_space_station_13_on/
no way currently, most of ss13 servers require at least ie10 now and wine doesn't support later ie versions almost at all.

You can always make a windows 7 VM or somethin' like that, then you can play spessman game without issues (mostly).
