It all depends on form content. Usually, double buffering helps. The idea to use MDI is bad.

First, double buffering.

Do you understand why it highly reduce flicker? If not, I can explain, but it would take some effort.

This is how to enable it: http://msdn.microsoft.com/en-us/library/system.windows.forms.control.doublebuffered(v=vs.110).aspx[^].

As to MDI, you can do much easier to implement design without it, with much better quality. MDI is highly discouraged even by Microsoft, in fact, Microsoft dropped it out of WPF and will hardly support it. More importantly, you will scare off all your users if you use MDI. Just don't. Please see:
http://en.wikipedia.org/wiki/Multiple_document_interface#Disadvantages[^],

I can explain what to do instead. Please see my past answers:
