text-scale-decrease changes text-scale-mode without font changes

[fatiparty--- via Users list for the GNU Emacs text editor]

I am using these two keybindings for chanding the font in emacs.  But I am getting text-scale-mode with a integer number decreasing (-1,-2,-3,...) when using "C-,".  Whilst for  "C-.", the integral number increasing.

Still the text height in the emacs buffer is not changing.

(global-set-key (kbd "C-,") 'text-scale-decrease)
(global-set-key (kbd "C-.") 'text-scale-increase)

Have done some more tests and still got the same problem.  Very strange.  Have been using
ivy and have now switched that off. Any suggestions on how I can do some progress on this,
as I am out of ideas.

Try using "emacs -q"

Things work out when using the command.  Still, I am using a fairly basic setup and cannot identify
a reason for failing with my setup.

AW: text-scale-decrease changes text-scale-mode without font changes

[Daniel Herzig]

Increasing and decreasing font size works for me (emacs 27.x.y [at least since 26] on pure Debian, Raspbian,  Guix, and  Windows 10)   using the built-in keybindings ‚ ~C-x C-+~, and ~C-x C--~, respectively.  I haven’t had a look though which functions are called by these bindings.

I am using GNU Emacs 27.2.  I get text-scale-decrease and text-scale-increase to work correctly 
after using "emacs -q" on the command line.

So something in your init files is messing that up.

Another font, perhaps? One that "resists" scaling?

You could slice up your init files and try a binary
search.

The problem is related to having the following call

(setq text-scale-mode-step 1.0)

Well, this is telling Emacs that the fonts are to be
scaled by a factor 1.0 at each step, i.e. leaves them
unchanged. So it is working as it should :-)

The default value is 1.2, which makes somewhat more
sense. Try another value (I guess you want something
greater than 1).

Thank you, resolved behaviour with a value greater than one.
