Hi,
Thank you for the log!
Firstly, we should try to find and isolate the source of your issue. For example, do you have the issue only in tablet mode or also with your mouse? Have you tried deactivating windows ink?
Is the problem happening on all Substance Painter projects or only your current one?
Lastly, would it be possible for you to test if the sliders controlling those parameters are working?
Thank you for your answer, in the hope I can help.
Regards,
Geoffroy SC
