Hi Kelly! Fellow Mac User here. 1. That font may be bad, with a flawed Ident. If it was a free font, I'd suggest finding an alternative. There are lots of Futhark fonts out there. 2. What sheet are you using? And where is this display generated? Throughout the game? Throughout the sheet? Only on spells? Only on spell output? The answer here might help pinpoint some bad CSS. 3. Are you using any extensions that might be affecting display, or the normal operation of Roll20? Try running the game under a private browsing window and see if the issue continues there.
