Load the code below to a M5Stack device.
then run for more than 30 min.
DO NOT PRESS ANY KEY WHILE RUNNING!
Do you see that the screen has changed the color?
It means that a keypressed event was catched.

Is this bug known?
maybe https://github.com/m5stack/M5Stack/issues/52 (2 years old!!!)

from m5stack import *
from m5ui import *
from uiflow import *
import wifiCfg

ip = wifiCfg.wlan_sta.ifconfig()

lcd.clear()
lcd.font(lcd.FONT_DejaVu18)
lcd.print('initializing...', 0, 0, 0xffffff)
wifiCfg.screenShow()
wifiCfg.autoConnect(lcdShow = True)

setScreenColor(0x000000)

def buttonA_wasPressed():
lcd.fill(0xff0000)
pass
btnA.wasPressed(buttonA_wasPressed)

def buttonB_wasPressed():
lcd.fill(0x00ff00)
pass
btnB.wasPressed(buttonB_wasPressed)

def buttonC_wasPressed():
lcd.fill(0x0000ff)
pass
btnC.wasPressed(buttonC_wasPressed)

Is there a workaround to avoid that?
Its absolutely useless if an key pressed event is catched, if no key was pressed!

Thanks ;-)
