Twinkle effects in playlist with C#

[MiSi]

Hi,

I would like to integrate the VLC activeX plugin in my own C# application. So I took Visual Studio 2013 and VLC 1.1.11. I created a new WindowsForms project, imported the VLC COM component (axvlc.dll) and dropped the component on my form. Then I created a playlist of pictures to be displayed on the component. Luckily, everything works fine - except:
When the playlist will be displayed on the GUI, there's a little twinkle effect between each picture. Between each picture, the component first will be colored grey for a couple of milliseconds, then colored black for a couple of milliseconds, then the next picture will be displayed. Of course this behavior is a little bit annoying.
Does anybody know how to avoid this behavior?

Thanks in advance
