Blur:

set DoubleBuffered = True to all forms including with MDI and use System.Threading.Thread.Sleep(100)

between switching the forms

 

Blue Bar: i think "Title Bar"

change FormBorderStyle property and decide which option do you want to...

Unfortunately, WinForms has some very annoying issues that are hard to work around, especially when it comes to MDI. The title bars flicker or animate when you have an MDI child maximized and you activate another MDI child or open a new MDI child. Is this the problem you are having? If so, there are a couple of partial solutions on CodeProject. They fix the flicker issue when switching between child forms, but not when opening a new child form.

 

Workaround for flicker/flashing when programmatically activating MDI child forms is the solution I used. There is also A flicker issue in MDI applications which uses a different approach but has the same effect.
