I have just got my custom rom working and it seems that while using usb-c(dp mode) touch doesnt work correct, i can drag down on the screen and sometimes the shade will slide down but i can not press any buttons(settings, power), on the home screen i can not swipe or press any icons.
If i change over to HDMI then it mostly works but the screen turns on/off all the time(only happens with HDMI).
