FAQ No zero pressure

Part of the MyPaint FAQ.
When I use my tablet, the cursor is trailed by a line when it's not pressed down: can I fix this?
Sometimes a tablet might be sending false pressure data from the stylus: maybe the sensor is constantly pressed a tiny amount, or there is a configuration glitch. Sometimes it helps to replace the nib of the pen with a spare one. If this doesn't work, you can fix this by adjusting the Global Pressure Mapping setting in Edit → Settings.
- Adjust Global Pressure Mapping in Edit → Settings.
- Click on the line to create a new node.
- Move the node to the bottom of the coordinate system.
- Move the node on the left-right (horizontal) axis while alternatively testing your tablet on the canvas.
Tip: If you find it hard to find the right setting, you can get the pressure values MyPaint (in version 0.9.0 and newer) sees by going to Help → Debug → Test Input Devices….
