Yeah, Windows is passing your tablet signals as a mouse. If you can draw without a problem then it isn’t so bad, also I believe the precision of the tablet doesn’t change. Then you shouldn’t worry too much.
The only thing ‘bad’ is that you will have no pen pressure. So it’s up to you if you want to try and resolve this hiccup.
For now you can change Krita to Windows 8+ (Windows Ink) and your Gaomon program to Active Windows Ink. Close Krita and restart your PC.
Usually this solve this issue with Windows passing the tablet as a mouse.
It is very unfortunate. What you have to do it only revert back to the previous settings.
In the Gaomon program uncheck the option Activer Windows Ink
In Krita check the WinTab option and close Krita
Restart you PC. Just to be sure.
At least we know this way your tablet is going to work. However you will not have pen pressure.
There isn’t much more I can think to solve this problem, but you said the drawing was better even without pen pressure. So maybe it is a good enough compromise.
This is perfect.
Krita is ‘seeing’ your tablet as a tablet. Now you definitely has all the features advertise by your tablet manufacturer. You can test the brush b) Basic-5 Size and see for yourself how the pen respond to pressure.
