Type of device* : Laptop with touchscreen and pen / stylus
Brand and version of the device: Lenovo ThinkPad X1 Yoga 5th Gen (Type 20UB 20UC), Intel® Core™ i7-10510U CPU, 16GB RAM, IntelHD620, screen 3840x2160 touchscreen, pen / stylus
System** : Windows 10 Pro 64
The brushes such as Basic-5 size produce a clean smooth line if using the mouse, if using the stylus they produce weird looking discontinuous blotched traits. The snapshot is below: the top four line are drawn using brush Basic 5-size with the mouse, the bottom four lines are drawn with exactly the same settings using the stylus. Stylus works well in all other applications, for example Paint, GIMP, MS Words etc. etc.
Thank you in advance for all your help.
