So I removed the screen protector, and mtpaint works really well now.
but mypaint for some reason the half of the screen is not responding picking up on strokes(left side).
I thought it was a problem with my tablet but i don't think it is because it works in mtpaint.
I tried calibrating the screen, and still the left being difficult.
it does work when I do draw with my fingers instead of the stylus.
