Hi Robert,
Thanks for the explanation.
I don't have time to spend on that during the next weeks/months but
maybe one day...
Thanks.
Regards,
Vincent.

HI Vincent,
The frame lag is an unfortunate side effect to the way that osgFX
doesn't know how to render itself until it's queried the OpenGL
extensions/versions available.
osgFX is rather old now and code do with a revamp that addresses this
issues, but would need a form of up front extension checking that
requires a valid graphics context, so it rather pushes the current
decoupled design where the scene graph doesn't get involved with
construction of contexts. Feel free to dive in and come up with a
proposal.
Robert.

Hi all,
This a very strange and unexpected bug :
Applying an osgFX::Scribe effect on a node, we can see a lag in the render :
If you get each frame a screenshot you can see :
*Frame #1*
Action : no action
Render : normal render of the node
*Frame #2*
Action : adding a osgFX::Scribe node as parent of the node to apply the
effect (done in a callback on root node)
Render : no node !
*
Frame #3*
Action : no action
Render : node with applied effect.
So during one frame, the node is not rendered at all... This is very
embarrassing if you take a screenshot automatically in post-render of the
frame where
you apply the effect...
Thanks for your help.
Regards,
Vincent
