I noticed a couple of things you might want to look into. First, you’re on Windows so you’re better off choosing wintab in krita and then go into the Wacom desktop center and turn off Windows ink in the pen settings. That will make Krita and your tablet match when it comes to deciding whether or not to use Windows Ink.
Be sure to close krita and restart it for these changes to take effect.
The other thing I noticed is you have practically zero pressure showing in the testing screenshot. You should be showing 10% 40% 80% and instead you’ve got .04% or tiny numbers like that.
One of our members just made a really awesome pressure testing brush preset. I’ll go and look for that and stick it in this comment in a couple of minutes. That might help you get everything adjusted properly.
