I have this weird graphics issue this when zooming in to my av for photos at higher altitudes (above 500m)...and I've tried several different viewers. When I zoom in for closeups, I can see all attachments on my av (including mesh eyes, ears, etc) seem to be "jittery", like moving up and down slightly. I'm wearing a mesh body and head, but I don't notice this happening at ground level, only in my skyboxes/platforms. Anyone else seen this?
