Simple Plugin Demonstrates Render Bug

[23skidoo]

I'm about to post some code. Just build it, stick it in the plugin directly, and run config to initialize it or whatever. It doesn't need a skin file.

So anyway, here are some steps to take to demonstrate the problem:

1. From the main men, select Interference (this is the new plugin).
   
2. Black screen. Alternates between "true" and "false." About every second. What we'd expect.
   
3. Press [back/exit] (or escape). Now you're back at the main menu.
   
4. Select Live TV. Wait for it.
   
5. Now press [menu] (not sure what the keyboard equivalent is). Now you're back at the main menu, with the Live TV playing "in the background."
   
6. Now select the Interference plugin. The screen never refreshes. Stays the same. And yet, render() is called.
   
7. Press [back/exit] to return to the Main Menu, close Live TV, then go back into the Main Menu and run the Interference plugin again. It alternates, as expected.

It's a mystery. Who will solve it first?! lol

Oh, I almost forgot.

Code:

public class Interference_Task : IMenuTask
    {

        private string m_Message = "Hiya.";
        private string m_Name = "Interference";
        private bool m_TickTock = false;

        public Interference_Task()
        {
        }

        #region IMenuTask Members

        void IMenuTask.Activate()
        {
        }

        void IMenuTask.Deactivate()
        {
        }

        System.Windows.Forms.Form IMenuTask.GetConfigFormInstance(System.Xml.XmlDocument document)
        {
            return null;
        }

        void IMenuTask.OnClick(System.Drawing.Point location)
        {

        }

        void IMenuTask.OnDoubleClick(System.Drawing.Point location)
        {

        }

        bool IMenuTask.OnKeyDown(System.Windows.Forms.KeyEventArgs e)
        {
            if (e.KeyCode == System.Windows.Forms.Keys.Escape)
                PluginHelperFactory.getPluginHelper().ReturnToMainMenu();
            return true;
        }

        void IMenuTask.OnMouseWheel(System.Windows.Forms.MouseEventArgs e)
        {

        }

        string IMenuTask.getDescription()
        {
            return "Smell the purple concrete";
        }

        string IMenuTask.getName()
        {
            return m_Name;
        }

        string IMenuTask.getSkinSubdirectory()
        {
            return m_Name;
        }

        System.Drawing.Image IMenuTask.getTaskImage()
        {
            return null;
        }

        bool IMenuTask.needsRendering()
        {
            return true;
        }

        System.Drawing.Image IMenuTask.render(out bool requiresMoreRendering)
        {
            requiresMoreRendering = false;

            m_TickTock = !m_TickTock;
            m_Message = m_TickTock.ToString();

            Bitmap canvas = new Bitmap(720, 480);
            Graphics g = Graphics.FromImage(canvas);

            g.Clear(Color.Black);

            RectangleF textArea = new RectangleF(0, 0, canvas.Width, canvas.Height);

            StringFormat strFormat = new StringFormat();
            strFormat.Alignment = StringAlignment.Center;
            strFormat.LineAlignment = StringAlignment.Center;

            g.DrawString(m_Message, new Font("Tahoma", 18), Brushes.White,
            textArea, strFormat);

            return canvas;
        }
        #endregion
    }

And I have confirmed that substituting recorded TV for live TV causes the same symptoms. But Net Radio does not interfere with the rendering.

I uploaded a compiled assembly with this test plugin in it. There's a generic one in there called "Hello World" too. Just ignore that.

Ok, I've fixed this for the next release.
