.NET Framework's FolderBrowserDialog is not DPIAware?

Question

I've created a simple application with VisualStudio 2022, and .NET Framework 4.8. I have two monitors: A (100%, 96DPI), B (175%, 168DPI).

I did also defined dpiAwareness to PerMonitorV2 in app.manifest.

I added only one control: FolderBrowserDialog:

And I have this code in form's click event handler:

private void Form1_Click(object sender, EventArgs e)
{
    folderBrowserDialog1.ShowDialog();
}

Folder browser looks great at first:

However, if I move it between the two monitors, it gets corrupted:

How can I make this system form also DPI-Aware?

Answer 1

Setting in application config is one thing.

But there are other things to be taken care.

• Declare compatibility with operating system.
• Also enabling visual styles. Application.EnableVisualStyles() should be called first in the entry point (your main function).

The below link has description about the above said settings. In the below link look for Configuring your Windows Forms app for high DPI support
