actual display.

I am not sure if there is anything I made mistake.

Is there any switch that I can turn on double buffer function?

Looks like you don't have the other side anchored to the splitter so that it will move left.

Such drawing artefactos have came with Windows 10. In such cases, I change the ResizeStyle of the splitter from rsUpdate to rsLine or rsPattern which avoid redrawing the attached controls while dragging. This does not look as chique as the updating splitter, but definitely better than the garbled partially repainted display.

Try to set DoubleBuffered property of this Form to True.  It helps in some cases, i guess.
