On iOS 11 I am seeing dead zones in the 60 or so pixels around every edge of the screen. Touches do not register here until after you hold them for nearly a second. It looks like this is due to iOS overlaying a GestureRecognizer on the edges of the screen to detect multitasking and dock swipes. There are some discussions online for iOS app developers on how to detect touch even with these in place. Note that I have tried reading mouse_x, mouse_y, device_mouse_x, device_mouse_y, device_mouse_x_raw, and device_mouse_y_raw along with mouse_check_button and device_mouse_check_button. All of these methods exhibit the same behavior. I have confirmed this is not happening with my same app on older versions of iOS. I really want to place controls near the edge of the display but this makes it very difficult. One interesting note is that on iPad Pro if you use the Apple Pencil it isn't an issue because the Pencil doesn't work for multitasking gestures therefore the pencil location is always detected properly immediately. Is there anything that can be updated in the iOS runner to work around this issue? Any other suggestions from anyone?
