Background image doesn't load on some computers with specific title

[nicolepeverley]

Our team has noticed an issue with the background image not loading on some computers when the dmg title is set to our app's name "Shift".

For unknown reasons, this issue doesn't seem to happen when we remove the "i" or add anything including a single space after "Shift". In our testing, the background image loads as expected with the following titles.

• "Shft"
• "Shift "
• "Shift 8.5.0.0"

Here are the contents of the appdmg.json file that causes the issue:

{
  "title": "Shift",
  "icon": "shift-logo.icns",
  "background": "dmg.png",
  "contents": [
    { "x": 448, "y": 344, "type": "link", "path": "/Applications" },
    { "x": 192, "y": 344, "type": "file", "path": "Shift.app" }
  ],
  "code-sign": {
    "signing-identity": "..."
  }
}

On only certain computers, the background image doesn't appear as seen below.
