I tried to use Paint.Net with a Huion tablet. However, there is often a delay of about 1 second or 1 cm before the press down is recognized, and during that time only the initial point is recognized. So it is not possible to draw a circle without the first part being a straight edge. Makes it useless.
The tablet works fine generally, an with plain Windows Paint.
I understand that touch sensitivity is difficult to support in .Net. But this is a different issue, simply using the tablet as a mouse does not work properly.
Thank you for providing Paint.Net. Microsoft should replace their inbuilt Paint with it!
