I found the following code which cancels the flickering in a WinForms application:
Protected Overrides ReadOnly Property CreateParams() As CreateParams
Get
Dim cp As CreateParams = MyBase.CreateParams
cp.ExStyle = cp.ExStyle Or &H2000000
Return cp
End Get
End Property 'CreateParams
The issue comes when "minimizing and maximizing the form, all controls are invisible. Removing &H2000000 fix the problem, but the controls start to flicker"
like it says in this comment on this question.
There's any update or way to solve this?
