fix RPI touchscreen not working with KIVY_BCM_DISPMANX_ID=4 #3642
OK...when running the GUI on the HDMI screen and the demo on the touch screen I see that the touch screen touches and movements are also driving the mouse on the HDMI screen. So there is no differentiation between those two. Is this the behaviour you had and fixed?
The Kivy demo screen drew just fine, but no mouse was visible and no touch was recognized. I wasn't using the HDMI screen -- serial console instead. FWIW, I used x2x to connect and saw the same thing. No mouse, no clicks were recognized, however clicks and drags took effect on the other windows.
