I installed Emacs with guix.

But the experience provided by the guix provided Emacs is not on par with
the one provided by the Fedora host rpovided Emacs

The menus and the buttons are slightly different but most important is the
minibuffer: It's a bit too small and hard to read.

Also the color in the guix provided Emacs is less bright

Because it's difficult to explain in words, I made a small screencast
showing the difference

The Emacs on the left side of the monitor is the Fedora one. The Emacs on
the right side is the guix one.

The audio is brutally cut, I'm sorry, I made my best with the screencast

Why are they different ? They share the same .emacs.d folder.

There must be something in the underneath X related libraries.

Could anything be done to improve the experience of the guix provided Emacs
?

Thanks
