The graphic being drawn is not displayed sometimes.

When triggered by the DrawingEnded event and executing the DrawEndedCommand to repeat the drawing, a strange phenomenon occurs:

During the drawing process, under normal circumstances, as you move the mouse, a graphic that changes in size with the mouse's position is displayed.
However, in some cases, while moving the mouse, the graphic being drawn is not displayed, and it only appears after releasing the mouse to indicate that the drawing is complete.

For instance, if I click the button "Draw xx" three times before starting to draw, it will not display every third time. In other words, it won't display on the 4th, 8th, 12th... drawing
If I start drawing after the first click, it will not display every other time. In other words, it won't display on the 2nd, 4th, 6th, 8th... drawing.

This phenomenon occurs in both the RichCanvasDemo and my own project.
Why does this phenomenon occur, and are there any solutions?

This could be an issue and I would need to investigate more on it. This is all I can say at the moment, I can't say why this happens and what's a quick solution at the moment.
