DP collision bug

[Cobalt]

Found this bug years ago which sv_gameplayfix_q1bsptracelinereportstexture cvar will cure and happens only in dedicated server mode, but I was curious if a mapper could tell me if there is something special about the brushes / planes on the maps that show this problem in those specific areas? In the video , e1m1 has the issue near the doors, and on e1m4 the area seems to be all above and below the bridge over the small pool of water. Do these brushes have any similarity?

Video showing bug happening on e1m1:


I believe other maps this happens as well, such as e2m3 seems to be one of the worst offenders that make it happen as well as a couple of others I cant recall right now.
