I am not sure if my case was understood, let me use artist-mode:

 +----------------------------+
 |                            |
 | I was changing this        |
 | during minibuffer edit     |
 +----------------------------+
 | I was also changing this   |
 | during minibuffer editd    |		-
 |                    	      |
 +----------------------------+
 +----------------------------+

If I would have larger screen I would put all necessary buffers around
and use them to get references for minibuffer input. Instead I was
switching buffers in upper windows during minibuffer edit. It is not
related to shrinking or completions. My minibuffer was not completing
rather just reading string. During editing I would go up and switch to
one image or other. I was in the loop of minibuffer editing of
multiple coordinates. Upon each editing the already set images in
upper windows would switch back where minibuffer was invoked
initially.

That forces me to use outside program to keep pictures on screen when
required and makes editing less useful.
