SUMMARY
Hello, I've been having some problems with the Krita software recently. You see, I use a Huion Tablet and whenever I try to draw, the line is a bit jittery and sometimes it freezes for a few seconds making me unable to draw. There's also an issue with the pressure sensitivity. Usually depending on the pressure I draw with my pen it creates a bigger or smaller line. But now, it doesn't seem to do that anymore.

I'm having the same issue. My PC had the latest windows update and boom, my pen pressure is gone.

I'm sorry, but that's not a bug in Krita. Please reinstall the Huion drivers. Check whether switching between wintab and winink (in Krita's settings) makes a difference. Krita just relies on the OS and the driver to get tablet events, and if it doesn't get those events, there's nothing we can do.
