Since Qt's tablet support is introduced I can't manage my tablet to work in Krita. I know that my tablet isn't supported but I managed to make it work with Official version of Krita 4.1.7 (choosing Windows Ink support in drivers and Windows 8 + Pointer input in Tablet settings). 1. Tested with Windows ink only Canvas and Scatchpad respond to pen. Pressure OK. Other controls don't respond or respond after pressing pen for a while and then button activates and opens a context menu. 2. Tested with native drivers Krita becomes responsive as it should but pressure doesn't work. Windows 10 pro 64 PC XP-pen Decco 01 tablet ADDITIONAL INFORMATION I don't know is this of any help: PS and Sketchbook work without problems when Windows Ink is turned on in drivers, but without pressure when turned off.
