I have Ubuntu 16.04.1 fully updated.
Sometimes when in Webstorm the autocomplete popup is shown the monitor that has WebStorm flickers for a couple of seconds every time I press a key on the keyboard, making impossible to digit something. I have to change application and wait some minutes before I can use Webstorm again.
I haven't seen the problem with other programs
