How to fix the gap

so i am using emacs in macos 12.3 with amethyst wm, but i am getting this gap with emacs. Any help is appreciated [https://imgur.com/a/C2sjUOu](https://imgur.com/a/C2sjUOu)

This might be a feature not a bug. For example, people patched i3 to become i3-gap.

Maybe `(setq frame-resize-pixelwise t)` could help.

Thanks! it worked
