Might be that here I'm using yet another program to handle that case.
'mouse-wheel-follow-mouse' should not be involved but please make sure

From what Noam described the flickering could be due to the tool bar.
What happens when you write
(defun open-test ()
(display-buffer-in-child-frame
(get-buffer-create "test child-frame")
'((child-frame-parameters . ((tool-bar-lines . 0)
(width . 20)
(height . 10)
(top . 200)
(left . 100))))))
instead?

Here are my results: Emacs frame partially covered by an Emacs frame: Nothing happens. Mouse input does not seem to go anywhere. Emacs frame partially covered by a Windows explorer window: Emacs scrolls normally, that is, in my case there is some flickering. But nothing like what happens with a child frame.

There's occasionally a rectangle which seems to repainted slower than its surroundings. That rectangle is lower down (closer to my desk than the ceiling) on my monitor than the child frame. Also, I guess the text it momentarily contains was previously behind the child frame in terms of z-order (although it's a bit hard to tell because the repainting is still too fast to really anything).

> I don't see it.
I have found that creating a child frame causes it to flicker a lot more.
Here is a video that shows what happens https://youtu.be/BsUqPpyAvVQ
To reproduce it:
1) Start runemacs -Q
2) Open a big C/C++ file (I used dispextern.h from emacs)
3) Run this code to create the child frame (in the scratch buffer)
(defun open-test ()
(display-buffer-in-child-frame (get-buffer-create "test child-frame")
'((child-frame-parameters . ((width . 20)
(height . 10)
(top . 200)
(left . 100))))=
))
4) In the C/C++ buffer eval (open-test)
5) Scroll with the mouse wheel up and down.
I don't know if this is the same bug or if it's related.
