Since Windows 8, Microsoft introduced a new API to use your tablet with Windows programs: the pointer API. Since Aseprite v1.2.19.1 you can configure what API do you prefer to use:

Tablet section

  • Windows 8/10 Pointer API: This option might be enough for most modern devices, you can give a try how your tablet works with this (might work better with this option than with Wintab)
  • Wintab: This is the default option at the moment to support pressure sensitivity on older systems (Windows Vista/7) and older devices.
  • Wintab (direct packet processing): This option might not work well in some devices, but might be useful in other devices to avoid losing packets and getting smoother strokes.

Pressing the OK/Apply buttons will change the tablet settings immediately, there is no need to restart the program.


It looks like tablet/stylus/pen devices are detected by device name/brand name on X11, instead by device capabilities.

There are some pre-defined IDs to detect a stylus, but it might not be enough (as it's indicated in #3176)

If Aseprite doesn't detect the pressure of your pen, since Aseprite v1.2.35 you can try to do these steps:

  1. Close Aseprite
  2. Run xinput --list in a terminal/console
  3. Check the output and see what device could be the one related to your stylus (output example)
  4. Open aseprite.ini file in the preferences folder
  5. Search the [general] section and add the name of your stylus in a x11_stylus_id option (the name must appears just like in the first column of the xinput --list output):
    x11_stylus_id = Your Stylus Name
  6. Save the file and start Aseprite

Please inform us if this does work for your case adding a new comment in #3176 indicating the name of your device.
