So after the recent braver update, NGS hairstyles have been showing this weird white outline around character heads:
Seeing this on both players and NPCs. I asked a few friends and they are not having this visual error, so I tried revalidating files through steam, updating my graphics drivers, and toggling various graphics settings in the game. Further, the outline is only visible on NGS hairstyles, classic pso2 hairs do not have the issue.
Update: Finding this only happens in virtual fullscreen. Changing the game to windowed removes the issue entirely, but going back to fullscreen brings it back.
