Your removed channel flickers because you didn't clear the buffer to
black, or leave the same contents in the front and back buffer.
Before deleting a channel you could clear the screen without calling
pfDraw in the draw callback for a few frames or you could freeze the
eyepoint and objects in it's scene for one frame so that the buffer
contents are equal.
Cheers,Angus.

"One of the best-known folk theorems of software engineering is that
60% to 75% of conventional software projects are either never
completed or rejected by their intended users. If that range is
anywhere near true (and I've never met a manager of any experience
who disputes it) then more projects than not are being aimed at goals
which are either (a) not realistically attainable, or (b) just plain
wrong."
