So while using safari on buy MacBook Pro 13" 2017 I been having a weird issue with the screen saver. It seems to only happen when I am using safari. The screen saver will turn on at the time I have set it to even though I am moving the mouse and using keyboard. I do have my MacBook plugged into a monitor and I am using an external keyboard and mouse. Not sure if anyone has any ideas or if it's just a glitch.
