Image corrupted after zooming - image

Question

I am reading color frame from Kinect V2 sensor using Microsoft Kinect SDK v2. I am copying the frame data in a byte array, which is later on converted into EmguCV Image. Below is the snippet from the code-
// A pixel buffer to hold image data from the incoming color frame
private byte[] pixels = null;
private KinectSensor kinectSensor = null;
private ColorFrameReader colorFrameReader = null;
public KinectForm()
{
this.kinectSensor = KinectSensor.GetDefault();
this.colorFrameReader = this.kinectSensor.ColorFrameSource.OpenReader();
this.colorFrameReader.FrameArrived += this.Reader_ColorFrameArrived;
// create the colorFrameDescription from the ColorFrameSource using Bgra format
FrameDescription colorFrameDescription = this.kinectSensor.ColorFrameSource.CreateFrameDescription(ColorImageFormat.Bgra);
// Create a pixel buffer to hold the frame's image data as a byte array
this.pixels = new byte[colorFrameDescription.Width * colorFrameDescription.Height * colorFrameDescription.BytesPerPixel];
// open the sensor
this.kinectSensor.Open();
InitializeComponent();
}
private void Reader_ColorFrameArrived(object sender, ColorFrameArrivedEventArgs e)
{
using (ColorFrame colorFrame = e.FrameReference.AcquireFrame())
{
if (colorFrame != null)
{
FrameDescription colorFrameDescription = colorFrame.FrameDescription;
if (colorFrame.RawColorImageFormat == ColorImageFormat.Bgra)
colorFrame.CopyRawFrameDataToArray(pixels);
else
colorFrame.CopyConvertedFrameDataToArray(this.pixels, ColorImageFormat.Bgra);
//Initialize Emgu CV image then assign byte array of pixels to it
Image<Bgr, byte> img = new Image<Bgr, byte>(colorFrameDescription.Width, colorFrameDescription.Height);
img.Bytes = pixels;
imgBox.Image = img;//Show image in Emgu.CV.UI.ImageBox
}
}
}
The converted image is corrupted after zooming more than 25%. Please see below screenshots-
50% Zoom -
25% Zoom -
12.5% Zoom -

The < TColor> should be Bgra, you can confirm from the "pixels" bytes array.
edit:
As the intensity of the Kinect's color frame is 0, the image won't be visible, so I added this code to solve the issue, I hope there is a better (faster) way to solve it.
private void FixIntensity(byte[] p)
{
int i = 0;
while (i < p.Length)
{
p[i+3] = 255;
i += 4;
}
}
