It looks like after using fullscreen API on desktop the pointer’s position is defined incorrectly
After going into fullscreen all of the game buttons’ hit areas seem to be stretched over the buttons’ bounding boxes. It means that they appear to be in the wrong area and may not react on player’s clicks or react on clicks outside the buttons
A short illustration, based on @samme 's fullscreen example from http://www.html5gamedevs.com/topic/37279-can-phaser3-do-fullscreen/, can be found here https://codepen.io/kodedyukh/pen/GPryNP?editors=0110
In this example when you click the logo it turns red and back with the second click. And works fine before you go fullscreen.
In fullscreen mode when you press even outside the game canvas (on the right in front of logo, as on picture below) the logo goes red.
So any ideas on why does this happen and how it could be fixed?
