Icicles error: Cannot decrease the defualt face height more than it already

Question

On icy-mode is enabled, I keep getting following error while I am typing, which makes it very difficult to type:

Cannot decrease the defualt face height more than it already.

Example case:

M-x => ibuf [TAB] and when enter a character it gives the warning message.

[Q] Can I supress/fix this error?

Based on the windows lise sometime mini buffer also open vertically or horizontally.

My Setup:

(add-to-list 'load-path "~/.emacs.d/lisp/icicles")
(require 'icicles)
(icy-mode 1)

(set-face-attribute 'default nil :height 100)
(variable-pitch-mode t)

Answer 1

This solved my issue:

I added following line into .emacs file. (setq icicle-Completions-text-scale-decrease 0.00)

This was set to 0.75 on the icicles-opt.el file.

From the original file L2451:

icicle-Completions-text-scale-decrease 0.75
    "*Initial height decrease for text in buffer `*Completions*'. A value of 0.0 means the height is not decreased at all. This is used as
the argument to function `text-scale-decrease'. ```
