Wing IDE is missing most of its menu bar

As the title says. Only "Options" is visible, the rest of the menu is accessible (but not visible) by pressing F10.

dbusmenu-dumper gives:
{
  "id": 0,
  "children-display": "submenu",
  "submenu": [
      {
        "id": 1,
        "enabled": true,
        "label": "Options",
        "visible": true
      }
  ]
}
