C # panel .BackgroundImage + transparent Controls = flicker?

Question

I have a Panel with jpg BackgroundImage (with BackgroundImageLayout = Stretch ). In the Controls panel, I add several PictureBoxes with PNG, which has transparent borders. Displaying this does not give any problems, but moving (boxes are draggable) PictureBoxes does.

As a result, the motion of the PictureBox “violates” BackgroundImage and slows down performance. The faster I drag the field, the more it bothers BackgroundImage and vice versa.

How to solve this problem?
