    I've a display Ribbon popup's RadGalleryElement between Windows 10 build 1511 and 1607  

    See File-Attachs

    Screenshot on Windows 10 1511 : http://creiler.free.fr/1.jpg => NO BUG

    Screenshot on Windows 10 1607 : http://creiler.free.fr/2.jpg => DISPLAY BUG

    I tested on 4 differents computers (Lenovo and Dell) : 2 Windows 10 1511  and 2 Windows 10 1607

    No specific code, simple filling

    I tried use DropdownOpening Event but no success :

    Private Sub RGEProducts_DropDownOpening(sender As Object, e As System.ComponentModel.CancelEventArgs) Handles RGEProducts.DropDownOpening
            Dim iWindowWidth = Me.Width
            Dim iWindowHeight = Me.Height
            With Me.RGEProducts
                If .Items.Count > 0 Then
                    With .GalleryDropDown
                        .AutoScroll = True
                        .SetAutoScrollMargin(0, 0)
                        .MaximumSize = New Size(540, 720)
                        .HorizontalAlignmentCorrectionMode = AlignmentCorrectionMode.None
                        .Size = New Size(540, 720)
                    End With
                End If
            End With
        Catch ex As Exception
            MsgBox("RGEProducts_DropDownOpening: " & ex.Message, MsgBoxStyle.Critical)
        End Try
    End Sub


    A little bit information on origin of this issue :

    I haven't this display bug, but my computer use a AMD Graphics Card with last driver 

    All other PC with windows 10 1607 use Intel Graphics Card with Version Driver with last driver intel (DELL)

    and 26/11/2012 (Lenovo)

    Maybe it's a issue in DirectX API and DirectDraw function with driver Intel with Windows 1607 and ribbon component !!!

    After DirectX update , same issue.

    I can't solve this issue !!!

    Do you know this issue ?

    Do you can help me ?

    Hello Cyril,

    Thank you for writing.

    First I would like to kindly ask you not to open multiple threads with the same question. Your other thread has already been converted to a support ticket and you can find it in your Telerik Account.

    For the sake of the community, I have to add that we performed tests on exactly the same machine as stated by you and we could not reproduce an issue with the gallery element dropdown. Since we are going to need your project to perform a further investigation I suggest that we continue our communication in your ticket.

    I hope this helps. Should you have further questions please do not hesitate to write back.
