MBP seems to take screenshot automatically
Using 2015 MBP El Capitan 10.11.3
The computer seems to randomly take an automatic screenshot (screen flickers and screenshot sound is heard)
This usually happens when on Safari. I use VPN at times but this also happens when I am on on VPN.
It gives me the creeps as I feel someone is aware of what I am doing.
Any insight would be appreciated.
