Gas mask glitch

So I was playing a normal match and I realized that if you put on your gas mask and put if away at the beginning of a round and swap to your pistol you will have a optic sight going horizontally through your gun. Let me know if you have experienced this.

I just tried recreating this glitch in game and it didn't work for me 😞

I've been getting something similar to this. It appears to happen only at the start of the round, when I first load in. When I put the gas mask on I get two floating rear sights (Or partial edges of the mask? Can't tell) Appearing in the middle of the screen. If I wait a small amount of time it seems to resolve itself.
Related, weapons, head models etc sometimes do not load in early in the round. Typically this resolves itself before the round starts.
