Editor window jumping between client and server

I was trying to test my game for multiplayer, but as soon as I set the player count to 2 the controls got messed up and the secondary window jumped between my characters. After that I tried adding a 3rd character and the issue persisted(2nd and 3rd window jumped between all 3 characters). I was not sure whether I messed up somewhere so I tried it with the 3rd person example and the same issue replicated there.
I have no idea how to fix this.
I am using an Intel Core i7-4702MQ 2.2GHz CPU and an NVIDIA GeForce GTX 760M GPU and I have 16 GB RAM.
I hope this this issue will be fixed soon.

As it seems this error only replicates on my laptop. Huh…
