enemy markers showing trough walls at beginning of match

Hi,

I've noticed that at the start of each map, within a minute, I can see markers for a split second through walls, floors and ceilings. just for a split second. hard to describe as english is not my native language.

I dont know exactly where the enemy is, but I know they're close and in the direction that I saw the markers. the markers appear to be hollow, so outlined, not full orange as you spot enemies in the open.
