I am using windows, and when I hold the blue color it's getting filled real slowly like maybe every 10s and sometimes slower to just fills one line, that has must taken me to in hours when I mentioned it to you in my first comment, but I have noticed somethings. First, there are sudden jumps in the blue color, at that time when it took me 30min it jumped 3 times, plus I tried this morning to test it and it jumped 5 times. The second thing. These jumps have something with either the keyboard or the mouse, because if I tried scrolling my mouse or pressing the keyboard, the jumps starts to become more often. And thanks for the help :D
