If the user has set show mouse set to true and clicks the screen the Get mouse x and Get mouse Y will no longer return anything other than 0.0
Additional notes: This does not appear to be a regression. However, the issue in 4.10.4 acted a little differently
In 4.11 the Mouse X/Y will not be returned after clicking
In 4.10.4 the Mouse X/Y does not return unless the user is holding down a mouse button
Expected: The nodes would continue to return the mouse information
Result: The mouse information is no longer given after the user clicks the screen
