The reason for the artefacts is that the entire surface isn't redrawn when the form is resized; only the necessary parts are. The generally best solution is what you don't want to do, calling Invalidate on each resize. However, if this is in fact your situation, just use a PictureBox instead. If it's not, you might consider overriding OnPaint in your form instead, and using this.SetStyle(ControlStyles.ResizeRedraw, true) to do this automatically.
