Hi. The mouse works fine, but when using a pen tablet there is a slight delay before the line suddenly jumps leaving a small straight line and picking up where your pen is. I do not think it is a pen tablet issue. The pen tablet works fine on 3D Paint. It has to be a setting in Krita or an issue if the latest version (4.4.2). Any help would be much appreciated.

Which OS are you on? If on Windows, try disabling gestures and flicks in Pen&Touch settings. Also try switching Krita to Windows Ink in Configure Krita -> Tablet Settings (you need to restart your PC afterwards).

Thank you. Switching from "WinTab" to "Windows 8 + Pointer Input" fixed this problem.
For anyone with this issue, the above options can be found after opening the Krita software. Click on the Settings option at the top of the opened program. Configure Krita-Tablet Settings.
