I wanna draw with Grease pencil, but when I turn on the Radius Pressure, the lines disappear immediately.
and if I turn on the Strength Pressure, it draws nothing.
Not only the Wacom pen but also Mouse does too.
But in a new project file, it works correctly.
(I have already tried to Append the objects to new project, then it has the same issue.)
I set Tablet API - Wintab.
Blender version is 2.83
Anybody know about this issue?
Thank you in advance for your help.
