How to make emacs work well with tiling window managers?

Under some conditions Emacs will try to resize a frame if its not fullscreen or maximized.

(specifically default-text-scale, but I don't think its the only one).

This sends window-manager window (aka Emacs frame) resize commands, which get ignored, making the frame flicker when scaling fonts for eg.

Running toggle-frame-maximized solves this until the window manager moves the frame which resets Emacs internal state.

I tried:

(add-to-list
  'default-frame-alist 
  '(fullscreen . maximized))

Which works at startup until the frame is moved.

How to configure Emacs so it's always maximized, or so that plugins don't think it's possible to resize the frame?

Tested with spectrwm and notion window managers.

I suggest that you mention which window manager you are using. – mikado Feb 06 '19 at 16:32
You might want to set `frame-resize-pixelwise` to `t`, as it will prevent the window from resizing according to font size. It works well for me with dwm. – Feb 06 '19 at 17:29
@mikado notion / spectrwm, @DoMiNeLa10 doesn't resolve issue w/ `default-text-scale` – ideasman42 Feb 06 '19 at 21:13

Are you using the newest version of Emacs? Double buffering got added recently, and it effectively gets rid of flickering. – Feb 06 '19 at 22:49
@DoMiNeLa10 version `26.1` – ideasman42 Feb 06 '19 at 23:00
Can you give some command that triggers the resize? – Feb 06 '19 at 23:06
`default-text-scale-increase` - but flickering is mainly noticeable if you call many times, say if you bind to Ctrl-Wheel. – ideasman42 Feb 07 '19 at 00:59
Where does `default-text-scale` come from? I don't see it when using `emacs -Q`. – Lorem Ipsum Feb 07 '19 at 03:54
