I have serious trouble while I'm trying to draw: Line looks terible, pressure doesn't work, but everything is right in brush settings.
How should it work (and how it works in brush settings):

How it works:

I tried reinstalling but nothing changed. No problems when using Gimp / Onenote or any other software using pen input. It doesn't work correctly with any brush. At the beginning everything worked fine. It just stopped working without any reason. I'm sorry for all mistakes. I'm new on this forum and English isn't my native language.

Specs:
Krita 4.4.1 (4.3 - tried, same result)
Windows 10 Home 20H2
Ryzen 5 2400g / Radeon RX570
8GB DDR4 3000MHz, single stick
120GB NVMe SSD
Xp-pen g430s

Try reinstalling the tablet driver, installing an older version of the driver, or a newer version of the tablet driver.
