Weird lighting bug with token hp bars

I was in the middle of prep for my game and I suddenly had these dark triangles coming off of everything on my tokens page. I don't have dynamic lighting (as far as I know, I'm a free user), so it's probably not that. I tried fiddling with the legacy lighting, but no luck. My only other guess is some sort of memory leak?

You shouldn't even be able to fiddle with legacy lighting as a free user, so I'm guessing this is some hardware/software weirdness that is conflicting with Roll20. Have you tried loading your game in another browser, or in a private browsing window (to eliminate most extension conflicts)?

The legacy lighting thing I was messing with was the fog of war. I closed and re-opened Chrome, and it seems to have fixed it, but I'm still wondering how it happened in the first place. If I find out more, I'll update here.

Gotcha. Also, if it occurs again, fill out a  Help Center Request  for dev attention. Posting here is more likely to alert Concerned Citizens like me than anyone who can do anything about it. FWIW, there is another thread reporting similar behavior, so cross your fingers. :)

Hi! I am having the exact same problem! I'm a Plus account user and am using dynamic lighting in my game. I also encountered the same issue when playing in another user's game, also Plus account user with dynamic lighting. I find that the problem reoccurs. I've also started to have a weird jagged black lines effect in a similar manner. It's awful! I'm pretty new to the Roll20 community, processes etc. so grateful for any help. Here are my screenshots:

I've submitted a bug as noted in the post above.
