Hello Miles,
In the project that you have attached you are using System.Windows.Forms.Panel not NUIPanel.
Anyway, one suggestion that you can try is to create class that inherits from Panel and in the constructor set DoubleBuffered to true.
Than use this class for your panel. This should reduce flickering.
public class MyPanel : Panel
{
public MyPanel()
{
DoubleBuffered = true;
}
}Please, let us know if the problem persist.
Best Regards,
