How to Maintain a Persistent Red Background in a Windows Forms Application Using Emgu CV

Question

I'm developing a Windows Forms application using C# and Emgu CV where I need to maintain a persistent red background while dynamically overlaying images captured from a webcam. Despite setting the background to red using Graphics.Clear(), the red does not appear as expected, or gets overridden by subsequent drawing operations.

Here's the simplified version of my paint event where I set the background:

protected override void OnPaint(PaintEventArgs e) {
base.OnPaint(e);
using (var g = e.Graphics)
{
    g.Clear(Color.FromArgb(187, 30, 16)); // Traffic Red
    g.DrawImage(_currentFrame.Bitmap, new Point(0, 0)); // Drawing the webcam feed
} }

Despite this, the background isn't consistently red as intended. The webcam feed is supposed to appear over the red background, but it seems to cover it entirely or the red doesn't show at all. How can I ensure the background remains visible and the images are correctly layered on top?

Any insights or suggestions would be greatly appreciated!
