Blank space at the top when opening a GtkComboBox

[Nicolò Chieffo]

This happens only with GtkComboBox, and not GtkComboBoxEntry.

There is a scenario in which when you open the combo box you'll get a blank
space it the top.
This is beacause the first entry of the combo box items is placed just below
the main widget, while the menu background is expanded accordingly to the
number of items.
The result is really unpleasant to see.

Note: in the screenshot there is also a GtkComboBoxEntry, just ignore it.

Thank you for your bug report, setting triaged for know since you opened a new upstream bug and an hunderpapercut task but it's a well known issue with quite some duplicates in launchpad, the bug has likely been marked as invalid though because upstream doesn't consider it as a bug but a design issue.

yes, this bug is duplicate of bug #17591
sorry, but as you can see the other bug title was too app specific, so I couldn't find it using my search terms
