Try switching between wintab and windows ink both in Krita settings (settings > configure Krita > tablet settings) and in your driver (so that both of these are the same.
I use the same tablet as well. I dont have this problem although i dont really update the driver if it works xD so you can try to reinstall a previous driver and see if this fixes the problem. I use the version 1.6.0 of the PenTablet driver. Also in whatever system i used the driver and my tablet , t only worked properly with windows ink activated…
try this driver… I had no idea they were going to make a new one with new ui and stuff… Ill be checking it out and see if it causes the same problem to me.
It might be a obvious (and somewhat) stupid suggestion but are you sure that you are using the same brush as before? some might have settings that causes an effect like that
I’ve fixed it by disabling windows ink on the tablet driver application. Though changing krita windows ink and wintab didn’t really change anything, thanks for the help though!
