Users often experience flickers when loading forms or during other operations. To minimize this flickering, enable double buffering on the form, as illustrated below:

// Activates double buffering 
this.SetStyle(ControlStyles.DoubleBuffer |
   ControlStyles.OptimizedDoubleBuffer |
   ControlStyles.UserPaint |
   ControlStyles.AllPaintingInWmPaint, true);
this.UpdateStyles();

When DoubleBuffer is set to true, drawing is performed in a buffer. After it completes, the result is output to the screen. UserPaint and AllPaintingInWmPaint should also be set to true.
