New file. I try to draw with any brush using a pen (stylus). 
Then the magic begins: 
1. the cursor is rotating - it starts to rotate when the pen is near the screen and not even touched it - then, when you touch the screen the rotation is stopped, but when you try to draw a line the cursor is rotating
2. you cannot just draw a line - the outcome is unpredictable - it can work or nothing can happen, then you must pick another brush and then it could work; or then it can stop working with the same brush - then you can try to pick another color with the same brush - it may help (or may not)
3. if you are lucky and you are still able to draw lines with some brush and you want to change the color, you can pick another color, but the color of new line wouldn't change - you should pick another brush - then that another brush will draw the line with new color
4. if you are still lucky and able to draw lines, then there is some lagging in the drawing process and some mistakes about tip of the pen position: the program may freeze for a couple of moments and then draw the complete line, BUT it can draw another "tail" of that same line - tracing the pen when it is already above the display surface and not touching the screen. Very funny %)
5. some lines mismatch the size of their cursors (the scale factor could be like 5-10 times)
