After keypress there is round blue icon on the screen and it stays forever... (screen shot attached). Touchscreen is working correctly - there is no icon after I press the screen. The problem appears when I use USBKeyboard attached to raspberry. This icon can't be moved.
Any idea what is wrong ?
My configuration : KivyPie + RaspberryPi v2 + OfficialTouchScreen
config.ini :
[input]
mtdev_%(name)s = probesysfs,provider=mtdev
%(name)s = probesysfs,provider=hidinput
