Hello, Kerry,  
 
Thank you for the provided files. But it is not clear enough whether in the Designer file you use the custom RadImageEditor's implementation. That is why I have updated the sample project in a way to apply the workaround. The attached gif file illustrates the behavior on my end. 

Could you please give it a try and see how it works?

I am looking forward to your reply.

Excuse my ignorance...

I added your code to the project and I still get the out of memory error. Attached is the updated RadForm1. It is not calling the override at all. Maybe because I am not calling DrawShape?

Thank you for your help!!!

The main thing is that you can duplicate it. If I need to wait for an update that is okay. I can tell people to just 2 to 3 things max for now.

Hello, Kerry,  

Thank you for reporting this issue. I confirm that this is a memory problem in the drawing logic of the shape in RadImageEditor.

I have also updated your Telerik points.

Currently, the possible solution that I can suggest is to use the following custom RadImageEditor:

Public Class CustomImageEditor
    Inherits RadImageEditor
    Protected Overrides Function CreateImageEditorElement() As RadImageEditorElement
        Return New CustomImageEditorElement()
    End Function
End Class
 
Public Class CustomImageEditorElement
    Inherits RadImageEditorElement
    Public Overrides Sub DrawShape(shape As Drawing2D.GraphicsPath, fill As Color, stroke As Color, borderThickness As Integer)
        If Me.CurrentBitmap Is Nothing Then
            Me.OpenImage()
            Return
        End If
 
        Dim destRect As Rectangle = New Rectangle(0, 0, Me.OriginalBitmap.Width, Me.OriginalBitmap.Height)
        Dim destImage As Bitmap = New Bitmap(Me.OriginalBitmap.Width, Me.OriginalBitmap.Height)
        destImage.SetResolution(Me.OriginalBitmap.HorizontalResolution, Me.OriginalBitmap.VerticalResolution)
 
        Using graphics As Graphics = graphics.FromImage(destImage)
            graphics.CompositingMode = CompositingMode.SourceCopy
            graphics.CompositingQuality = CompositingQuality.HighQuality
            graphics.InterpolationMode = InterpolationMode.HighQualityBicubic
            graphics.SmoothingMode = SmoothingMode.HighQuality
            graphics.PixelOffsetMode = PixelOffsetMode.HighQuality
            graphics.DrawImage(Me.OriginalBitmap, destRect, 0, 0, Me.OriginalBitmap.Width, Me.OriginalBitmap.Height, GraphicsUnit.Pixel)
 
            Using brush As SolidBrush = New SolidBrush(fill)
 
                Using pen As Pen = New Pen(stroke, borderThickness)
                    graphics.CompositingMode = CompositingMode.SourceOver
                    graphics.FillPath(brush, shape)
                    graphics.DrawPath(pen, shape)
                End Using
            End Using
        End Using
 
        Me.CurrentBitmap.Dispose()
        Me.CurrentBitmap = Nothing
        Me.CurrentBitmap = CType(destImage.Clone(), Bitmap)
        destImage.Dispose()
        Me.Invalidate()
    End Sub
End Class

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
