Hey there, I saw some people point this out with some ornaments before but I decided to go through every legendary helmet ornament I had on my hunter. I didn't play that much before Beyond Light but I looked at a total of 58 ornaments. First of all the issue is a random small piece on the floor next to your guardian if you select some helmet ornaments (seems to be older ones mostly). That is especially annoying when you are in third person (in tower if helmet enabled e.g.). I attached a video with a screenshot of all ornaments I went through. Out of those 58 the issue exists for 26 of them. That's almost half of them. Please bungie. This is so incredibly annoying.
