Comment 2 for bug 1264965

When setting the label for the icon, the maximum size can also be set (to tell the indicator framework how much room the label may take up). So I believe the solution is to call set_label( labelText, guide ) as per https://lazka.github.io/pgi-docs/AppIndicator3-0.1/classes/Indicator.html#AppIndicator3.Indicator.set_label.

As an aside, the maintenance of this indicator has been taking up by another developer at https://github.com/fossfreedom/indicator-sysmonitor.
