Description Jiri Koten 2016-08-10 12:25:39 UTC
Description of problem:
I'm unable to select a Time Zone with mouse from the list and scrolling doesn't work either. Keyboard input works but It steels the focus and I'm unable to change windows or go to overlay in gnome-shell until I escape the list. 

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Go to Evolution Preferences > Calendar and Tasks 
2. Uncheck "Use system time zone" and  click Select 
3. Click on the Selection drop-down menu and try to select a time zone

Actual results:
cannot select any time zone with mouse or scroll the list

Expected results:
I'm able to scroll the list and select the desired time zone with mouse

Console output shows following gtk-message.

Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged.

Created attachment 1189670 [details]

Thanks for a bug report. I can reproduce it too, out of the evolution with this simple code, using gtk3-3.14.13-20. The first line of the attached test-gtk.c contains a command line to compile and run it.

The problem is the CSS style change, the appears-as-list property set to 1. I can easily comment out the code in the Evolution, but it doesn't scale, because other applications could be still broken, thus I'm moving this bug to gtk3 instead.
