Sorry if I ask something simple. I asked in Discord and IRC and for two days nobody has provied a solution.

I have the following form:

 public partial class Form1 : Form
 {
     public Form1()
     {
         InitializeComponent();
     }
     protected override void OnPaint(PaintEventArgs e)
     {
         base.OnPaint(e);
         e.Graphics.FillRectangle(Brushes.Black, ClientRectangle);
         Console.WriteLine($"OnPaint: {ClientRectangle}");
         e.Graphics.DrawString($"{ClientRectangle}", Font, Brushes.White, ClientRectangle);
     }
 }

When I run it, I see a black rectangle and a text above it with the coordinates.
However, when I’m resizing the form and I see a bunch of “OnPain: …” messages (which indicates that my OnPaint is being called) the initial text never changes.

What is going on here really?
