You can just replace original control with custom one which has protected DoubleBuffered property to true. E.g. for ListView it would be something like this:

internal class DoubleBufferedListView : ListView {

    public DoubleBufferedListView()
        : base() {
        this.DoubleBuffered = true;
    }

}

After that you just visit *.Designer.cs file and replace all mentions of native control with this one.

P.S. Instead of inheriting from control you can also set this property via reflection:

listView1.GetType().GetProperty("DoubleBuffered", BindingFlags.Instance | BindingFlags.NonPublic).SetValue(lsvReport, true, null);

It is not clean nor recommended but it requires no changes in *.Designer.cs files.
