Hi Isaac, glad to hear gegl-gtk was useful to you. I will try to check our your node editor work soon. What exactly is the issue with nodes with infinite bounds? I have not tested myself. Rendering of gegl:checkerboard sounds like some that should just-work, so I'd be happy to accept patches if it does not. If you have commit access to GEGL, you should have commit access to gegl-gtk. You can create a branch with proposed fixes there and I'll have a look. > I also have some interest in implementing the background node rendering (or > using someone else's implemention) that I saw mentioned in the comments.

Background rendering should already be possible by connecting to the GeglGtkView::draw-background signal.
