Comment 15 for bug 1578810

This issue can be observed in Xenial and Yakkety.

Install `gtk-3-examples` and run `gtk3-widget-factory`, look at the toolbar on Page 2, the last icon (tooltip 'Insert something') is disabled and should be dimmed, but is not.

I have also reproduced this issue on Xenial and Yakkety using:

  * Remmina (from the archive)
  * Wireshark (from the archive)
  * Eclipse (downloaded)

To reproduce with eclipse it has to be downloaded since the version in the archive uses GTK2+ for styling, and dims insensitive icons correctly.
