Blurry/flickering text rendering in Electron

At this point, I can only surmise that the blame lies with Electron (or some component thereof) for blurry text that additionally flickers softly in Atom. Bringing focus to code in the editor via mouseclick sharpens text for an instant, but which progressively softens into a blur over a period of roughly 1-2 seconds.

The various combinations of values in the following snippet (made possible in Atom with styles.less) have no effect:

atom-text-editor,
atom-text-editor.editor,
html {
    -webkit-font-smoothing: subpixel-antialiased;
    text-rendering        : optimizeLegibility;
}

Any leads on where to start with resolving this issue?
