For some reason, the Gtk About Dialog is not appearing properly. My class is a subclass of Granite.Application. The About dialog which comes as part of the elementary desktop is also with the same problematic appearance. I have not been able to produce this with a MVCE yet.
I have attached a screen shots of how the icon and the about dialog is appearing. After I do the build from source the icon and the about come properly. However, after installing from a Launchpad PPA it comes up with the incorrect looking About.
Appreciate any help on this.
