Hi,
I am porting clutter toolkit (clutk) to gles2. I found some problem between clutter/cogl rendering and raw gles2 rendering as mentioned below. It's appreciated that you can give some suggestions.
In part of ctk_effect_blur_paint() function, we do as following - create fbo with texture and depth buffer (raw gles2) - switch to this new fbo for rendering (raw gles2) - call clutter_actor_paint to render the actor to texture (clutter/cogl) - switch back to default frame buffer (raw gles2) - render above texture on screen for display (raw gles2)
With the sequence above, the actor cannot be displayed on screen. But if I replace clutter_actor_paint with raw gles2 rendering to paint a simple triangle, the triangle can be shown correctly. So I guess clutter_actor_paint didn't render to the new created fbo. is it related to the cogl fixed pipeline?
Thanks in advance!
Regards, Jammy
