SkiaSharp multiple draws eventually get's blury and loses color vibrance

For a game, I have a source and destination image; I iteratively draw parts of the source bitmap image over the destination (pure select a source rectangle and draw it onto the destination). This can occur thousands of times and eventually the image gets blurry and/or loses the color vibrance. Very noticeable over time.

I decode the image/jpg files into a bitmap using:

            var imageInfo = new SKImageInfo
            {
                AlphaType = SKAlphaType.Opaque,
                ColorType = SKColorType.Rgb565,
                Height = pixelLength,
                Width = pixelLength,
            };
            var bitmap = SKBitmap.Decode(sourceBytes, imageInfo);

I don't have alpha needs.

When I draw a rectangle from the source to the destination, I am using canvas.DrawBitmap(bitmap, x, y, paint) where paint is just a default "new Paint".

Any ideas why the image gets blurry and/or loses the color vibrance?

Thanks.
