I'm using the latest release of Krita (as of 02/01/16) with a Wacom Intuous small tablet and a few days ago my pen sensitivity just stopped working. I've configured the sensitivity curve on the advanced settings, uninstalled/reinstalled Krita, updated the drivers of my tablet, tried installing the 32-bit instead of the 64-bit Krita, but nothing is working. I've tried all of these things over and over, but my pen sensitivity is still not working. It works with every other program I have, and it's definitely not my tablet that is malfunctioning. I don't know what more to try, and I don't want to switch programs.
Does anyone know how to help me?

See if resetting the configuration does anything for you: https://userbase.kde.org/Krita/Manual/F ... figuration

Tablet pressure is super fickle right now on windows 10, and we're working really hard on the 3.0 release where we fully rewrote it, so hopefully that'll fix things. But resetting the configuration is the only thing I can think of for 2.9.10.
