Enabling DoubleBuffered as stax suggested above is helpful but it may not be sufficient.

In your form, add the following method override:

protected override void OnPaintBackground(PaintEventArgs e) {}

And, in the OnPaint method, paint the background yourself instead. If you don't do this, drawing the background and painting are separate events, and background painting has higher priority, meaning that it will happen earlier.

Furthermore, if you add child controls (like labels), they receive their own paint background/paint events. You may be able to disable the Label's background. If I do stuff like this, I tend to not use controls but paint the text and the images in one OnPaint.
