Issues in High Sierra about one-vibrancy HOT 2 OPEN

Here the Electron issue: electron/electron#10521

There doesn't seem to be a fix yet.

Temporary workarounds

1. A temporary workaround noted here is to go full-screen and then back to normal. Of course that's pretty annoying if it has to be done for every new window. Even automatically in Init Script.. probably feels too jarring.

2. Another option is to add back a background to the title bar:

@import "syntax-variables";
.one-vibrancy .title-bar {
  background-color: @syntax-background-color;
}

There are no rounded corners and doesn't really work with Title Bar: hidden tough.

Election carried out a fix, and seems it's taking effect in current Atom (1.26.1). The issue still presents on cold start, but if you fullscreen the window and switch back it will recover.
