How to flatten all objects on a form (winforms)?

Question

C++ / C#

How can I smooth all objects on the form? Moreover, during editing everything looks fine, but at startup it turns out terrible pixelation. Making a smoothed User Control for each element is not an option. I want to do everything at
once
. Do not offer.

I found how to fix the problem (maybe someone will need it).
You just need to optimize for a high DPI value.
In Program.cs we write:

[STAThread]
    static void Main() {
        if (Environment.OSVersion.Version.Major >= 6) SetProcessDPIAware();
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new MyForm());             //редактируем как нужно
    }

    [System.Runtime.InteropServices.DllImport("user32.dll")]
    private static extern bool SetProcessDPIAware();
