Hilft Dir das ein wenig weiter?
Zitat:
Determines whether the control’s image is rendered directly to the window or painted to an in-memory bitmap first.
property DoubleBuffered: Boolean;
Description
When DoubleBuffered is False, the windowed control paints itself directly to the window. When DoubleBuffered is True, the windowed control paints itself to an in-memory bitmap that is then used to paint the window. Double buffering reduces the amount of flicker when the control repaints, but is more memory intensive.
When a windowed control is a dock site and has an associated dock manager, it must be double-buffered
