This occurs in the single threaded version while using labels, specifically the "DOT ONLY" level of labels. Using the other label levels, I did not see this issue.
It was yellow when I was in friendly territory and red in enemy territory and would cut in and out. I could not determine a pattern.
I am using Oculus Quest 2.
