            Bug ID: 771117
           Summary: gtk3 3.21.5 broke displaying drop-down lists
    Classification: Platform
           Product: gtk+
           Version: 3.21.x
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: Backend: Wayland
          Assignee: gtk-bugs at gtk.org
          Reporter: kparal at redhat.com

                CC: rob at robster.org.uk, wayland-bugs at lists.freedesktop.org
     GNOME version: ---

With gtk3-3.21.4-2.fc25.x86_64, everything worked fine. With
gtk3-3.21.5-1.fc25.x86_64, all drop-down lists available in
gnome-control-center (e.g. in Power) are broken - if you click on them, they
display only an empty list, and the real values are hidden outside of the
visible area - you need to scroll to display them. Some of them can't be used
at all (the drop-down list under Suspend & Power button - other values can't be
displayed even with scrolling).

See the video to showcase the problem.

This happens on Wayland, but does not happen when I run gnome-control-center
with GDK_BACKEND=x11 GTK_CSD=1, and did not happen in previous gtk version
(tested with downgrade).
