Hi Alexander,

Yes, I also noticed this in the clutter reference manual. But no matter cogl_flush() is called or not, the results are the same. I think the frame buffer related operations in clutter_actor_paint affect this. I'm not so familiar with clutter, so I posted this topic here. :)

Regards,
Jammy

I was told that "after clutter_actor_paint to render the actor to
texture (clutter/cogl) the next step is to call cogl_flush ()".

Have you checked that cogl_flush properly called in this case?
