Brush stroke delay on multiple views

Using windows ink

After creating a new window on a new canvas and drawing with a brush with multiple views, there is a delay in drawing.

The first stroke is fine, but there is no response to the canvas for more than a second, and then there is a coherent drawing response.

It's very frustrating because I'm constantly checking the reduced image as I work.
(Navigator doesn't provide a detailed and accurate view.)

When using single view, there is no problem.

In addition, there is no problem when using wintab api, but I do not want to use it because the accuracy of the line drops to monitor resolution.

That's been resolved in photoshop 2021.
