Minor UI bugs in MacBook Pro with retina display

[lijingjiang]

Hey guys. I also have some issues about the UI. I have two Macs. One of them is old with non-retina screen, the other one is relatively new with retina display.

However, I have experienced some display issues in my retina mac. For example, the flycheck mode, when I put my cursor at the error position, the prompt window looks like this. Firstly it is not in the correct position, then the window is very small.

But in my old Mac, everything works normally just like the screen capture in readme

Also, for the neotree, in my old Mac, it looks like this

However, in my new Mac, the cursor is hollow when I placed it on the folder symbol

Both my old Mac and new Mac are running the OSX 10.12 system.

And the power line in the following picture looks pretty good, can the contributor share the configuration for this. In my retina display, if I am using the default power-line theme, it looks serrated.

Thank you very much.

Ah, cool! I hadn't thought of what might cause that first issue, with the tooltips.

What version of emacs are you using? Did you install it with brew? I no longer see the tooltips issue, having installed emacs with:

brew install --HEAD emacs --srgb --use-git-head --with-cocoa --with-gnutls --with-rsvg --with-imagemagick --with-spacemacs-icon

Unfortunately I can't help more than that, I can't remember when I last saw it or how I'd previously installed emacs.

The spaceline separators are listed here: https://github.com/syl20bnr/spacemacs/blob/master/doc/DOCUMENTATION.org#powerline-separators

I think the one you're looking for is 'contour', so in your .spacemacs config function, add the line

  (setq powerline-default-separator 'contour)

Hi @CarlQLange,

Thank you for your reply. My Emacs was installed using the same way instructed by readme The version of Emacs in both machines are 25.1.1.

$ brew tap d12frosted/emacs-plus
$ brew install emacs-plus
$ brew linkapps emacs-plus

I have tried your suggested way to install the Emacs, but seems like it may have some compatibility issue with spacemacs. I even cannot start it.

The error message is:

Symbol's value as variable is void: default major mode.

And, yes, the contour separator is what I am looking for. But my question is, how to config it to make it looks more smooth. Currently it looks like this (on my retina-mac)

My configuration for powerline is default, the scale is 1.1

   dotspacemacs-default-font '("Fira Code"
                               :size 15
                               :weight normal
                               :width normal
                               :powerline-scale 1.1)

Thank you for your help!

So the powerline thing, there's a longstanding issue with Emacs on Mac OS X and colour spaces. You can read about it here: milkypostman/powerline#54 and here: #4955

In short, you can add this to your user-config in .spacemacs and it'll workaround the issue

  (setq ns-use-srgb-colorspace nil)

Unfortunately, it breaks the overall colour space, so it kind of depends on whether you prefer a baby or a clean bathtub. :)

Personally I set my separator to

  (setq powerline-default-separator 'utf-8)

and just deal with the kind of ugly arrow separators :)

The issue you're facing with the install not working looks like you need to delete the elpa directory in ~/.emacs.d and let it redownload the packages, but no promises :)

@CarlQLange

Thank you for the update! The setting (setq powerline-default-separator 'utf-8) looks pretty nice! Highly recommend every Mac user (with retina display especially) try it :)

Also I have removed the elpa and reinstalled the Emacs using your instruction, but still have the same error.

FYI the newly installed version is 26, but when I using brew install emacs-plus for installation, the corresponding version is 25.1.1

Anyway, thank you very much!

Bump! Any solutions for this with latest version ?

The power line color issue has been resolved recently by a commit I made here. You need to set powerline-image-apple-rgb to t in order to enable the workaround.

If someone has a newer Macbook with DCI-P3 color space, I will appreciate if you let me know if the workaround is working for you or not.

I've also added a PR changing the docs to this fix: #9550
