Hi Francesc
Thank you for contacting Syncfusion Support.
This reported space is maintained to avoid cropping of its MetroForm appearance in maximized state and to ease resizing behavior in Normal state. This space has to be maintained. Please refer to this below screenshot.

We can a provide work around to hide this White background by setting MetroForm Backcolor same as Panel/container control Backcolor. Please make use of the below code example.
Code example
//Set the back color of and Panel
this.panel1.BackColor = System.Drawing.Color.Maroon;
public Form1()
{
InitializeComponent();
//Set the back color of MetroForm
this.BackColor = Color.Maroon;
} |
We have prepared a sample and screenshot for your reference and it can be downloaded from the below link.
