for some reason as soon as i launch chrome developer tools i get a grid overlay.. as depicted:
I tried uninstalling all the unnecessary chrome apps (that may be causing this).. and restarted chrome, but the grid still shows up.
Interestingly, as soon as I close google dev tools the grid disappears.. so it must be a behavior related to dev tools.. How Do I turn it off?
