CEGUIEffectsDemo sample

[shader]

Hello,

I have a problem about CEGUIEffectsDemo [CEGUI ver0.8.7 sample project]:
when I select OpenGL GUI Renderer, WobblyWindowEffect run well, as shown in the picture below:


but when I select OpenGL 3.2 Core Renderer, RenderEffect isn't shown as expected, as below:


Is there something I forgot to do?
Can someone point me to a link/tutorial explaining how to use CEGUI::RenderEffect?

I am sorry about my poor english, and look forward to your reply.
Thanks.

RenderEffect is quite low level in the way it works , and really all you can do here is looking at the implementation and the sample itself.

It is a vertex-based effect if I remember correctly.

That said, the sample of OpenGL3 Renderer should work as well. I faintly remember there is a bug on our bitbucket on this but I might easily be wrong. Feel free to open a ticket.

Just to confirm: it is not working on my system either. I think this might have never worked properly in OpenGL3 because no one implemented it to that extent
