Hi Infuzo,

setting the DoubleBuffer = true will not actually do it. So inorder for DoubleBuffer to work on your panel create a class and call it something like DoubleBufferPanel

in that class add this code

Public Class DoubleBufferPanel
Inherits Panel


Public Sub New()


Me.DoubleBuffered = True
SetStyle(ControlStyles.AllPaintingInWmPaint, True)
SetStyle(ControlStyles.OptimizedDoubleBuffer, True)
UpdateStyles()


End Sub


End Class

then build your application, and find your DoubleBufferPanel in the Toolbox and use that instead. That will remove all your flickering for the Panel

Thank Gunze, DoubleBufferPanel added to Panel at once after building project, and flickering does not bother me anymore.
