Cursor is slow. (VBE Canvas)

[ExtcreamHG]

Hello, I am using VBE Canvas to create a mouse cursor. I want to use a bmp file for the mouse cursor appearance, so I am using VBECanvas, but the mouse cursor is moving slowly. What should I do?

namespace AppendixExplorer
{
    public class Kernel : Sys.Kernel
    {
        public static VBECanvas canvas;

        [ManifestResourceStream(ResourceName = "AppendixExplorer.textures.AppendixLogo128x128.bmp")] public static byte[] appendixlogo;
        public static Bitmap centerBMP;
        [ManifestResourceStream(ResourceName = "AppendixExplorer.textures.cursor.bmp")] public static byte[] cursor_default;
        public static Bitmap cursor_defaultBMP;

        private int cursorX;
        private int cursorY;
        private int prevCursorX;
        private int prevCursorY;

        protected override void BeforeRun()
        {
            Thread.Sleep(2000);

            MouseManager.ScreenWidth = 1280;
            MouseManager.ScreenHeight = 720;

            MouseManager.X = 1280 / 2;
            MouseManager.Y = 720 / 2;

            System.Console.Clear();
            System.Console.WriteLine("Appendix Explorer booted successfully.");
            System.Console.WriteLine("Loading: Component");
            System.Console.WriteLine("Loading: CenterButton");
            System.Console.WriteLine("Loading: taskbar");
            System.Console.WriteLine("Loading: Textures");
            System.Console.WriteLine("Loading: background");
            System.Console.WriteLine("Loading: DONE");

            Thread.Sleep(3000);
            System.Console.Clear();
            
            canvas = new VBECanvas(new Mode(1280, 720, ColorDepth.ColorDepth32));

            canvas.Clear(Color.Blue);

            centerBMP = new Bitmap(appendixlogo);
            cursor_defaultBMP = new Bitmap(cursor_default);

            cursorX = (int)MouseManager.X;
            cursorY = (int)MouseManager.Y;
            prevCursorX = cursorX;
            prevCursorY = cursorY;
        }

        protected override void Run()
        {
            canvas.Clear(Color.Purple);

            Pen pen = new Pen(Color.Gray);

            uint pixelTaskbar = 70;
            var startpoint = 710;

            for (uint x = 50; x < 50 + 1170; x++)
            {
                for (uint y = 715 - pixelTaskbar; y < startpoint; y++)
                {
                    canvas.DrawPoint(pen, (int)x, (int)y);
                }
            }
            canvas.DrawImage(centerBMP, 63, 656, 50, 50);

            canvas.DrawImageAlpha(cursor_defaultBMP, (int)Sys.MouseManager.X, (int)Sys.MouseManager.Y);

            canvas.Display();
        }
    }
}

I'm confused. Is the cursor not moving as much as you'd like it to, or is there a noticeable amount of time between frames?
