Which version of Windows are you using?
Which graphics tablet are you using?
Have you tried installing the latest driver for the tablet?

Have you tried krita version 4.2.9 or the public 4.3.0 beta-1 from here:
https://krita.org/en/item/first-beta-of-krita-4-3-0-released/

Having said that, isn't palm rejection a function of the tablet and its driver?

Setting back to Reported then.

The palm rejection is something that the tablet driver should do, not Krita. You can remove drawing with touch in Krita - in Configure Krita -> General -> Tools -> Enable Touch Painting. If it doesn't fix the issue, you might want to disable touch in your tablet driver, or maybe use a drawing glove (glove helps since it prevents the tablet to find your skin and send events to Krita).

I will set it up to Upstream since it's not something Krita has a responsibility over.

Also you might get better results if you switch Krita to Windows Ink: https://docs.krita.org/en/contributors_manual/user_support.html#quick-solutions - restart your PC afterwards. This setting changes the standard Krita listens to tablet events with.

Btw I recently had the same issue on Linux (very annoying :( ). Then I noticed there is a new version of my tablet driver, I installed it and I haven't had issues even since - and there was nothing changed in Krita for that.
