iOS Mouse Position Lag in IOS

There seems to be an issue with Game Maker 1.4 getting the Mouse_x, Mouse_y or any mouse functions (mouse_check_button) anywhere near the left side of the screen (x position less than 50 pixels on the standard resolution of 750x1334 on an iPhone7 IOS device in portrait orientation). What I notice is that I have to hold down the mouse for about half of a second before the Mouse_x or Mouse_y position registers. However, If I move the mouse to any other position, or as soon as I release it, the coordinates register.

This makes life difficult that the left side of the screen behaves differently than the rest of the screen. Any presses on a button will not register due to this.

This can easily be replicated by performing a draw event to draw an object on the condition mouse_check_button is true. You will notice the object will draw instantly anywhere on the screen as soon as it is touched, however, as soon as you release and touch the left side of the screen and hold it, the image is lagged before it shows.

Just tested on an iPhone 4S, issue was not present. Maybe this is just an iPhone 7 issue? Will try and get another iPhone 7 to test on.
