I got myself the Windows Surface Pro 7 and wanted to use Krita to draw on it. While using my fingers to zoom in/out on the canvas it detects my fingers as the pen (i guess), and leaves me with my canvas full of little dots wherever I have been zooming. I tried to disable touch painting, but then it won't draw at all with my pen as if it can't detect it. Is there any way of not getting the little dots?
