On the issue of lags in the touch, and typing problems, I would like to give a suggestion to the developers, the action of fullscreen, could only work above the keyboard, in the region of the keyboard when it is open, would stop capturing the gestures, I believe It would help a lot.
With me it happens a lot to check the letter "q" finished executing the return gesture.
I also used this app for touch calibration, apparently it helped a bit in the delay.
