This just randomly started happening today. I’m specifically seeing it when in a FoundryVTT game. I would love to post an image of it but that doesn’t seem to be an option. I found a similar topic where people were complaining about this: Brave is adding a black border
… so it’s not just me.
This is on Mac OS Ventura 13.4.1
And Brave Version 1.52.129 Chromium: 114.0.5735.198 (Official Build) (arm64)
btw I really hate this community website – awful UX
