GtkScrolledWindow is mapped but visible child GtkScrollbar is not mapped

[Pojar Geo]

Ubuntu 13.04 (Raring Ringtail) Unity:

I don't now if this is GtkScrolledWindow or overlay scrollbars bug.

I got these warning in Totem Movie Player.

Test case:

Open totem -> Fill with items playlist panel from right of player until scrollbar show-up -> scroll to bottom of panel -> import more playlist items from playlist file, and this warning come out:

(totem:4060): Gtk-WARNING **: GtkScrolledWindow 0xb81ef2b0 is mapped but visible child GtkScrollbar 0xb82bc2a8 is not mapped

This bug appears to Rhythmbox Music Player if import playlist items from file:

(rhythmbox:4149): Gtk-WARNING **: RBPropertyView 0x9ee8000 is mapped but visible child GtkScrollbar 0xa08fe90 is not mapped

Thank you for your bug report, what version of Ubuntu do you use and what desktop environment?

I see this with evolution and overlay scrollbars disabled.

I disabled overlay scrollbars with:

$gsettings set com.canonical.desktop.interface scrollbar-mode normal

(evolution:13228): Gtk-WARNING **: GtkScrolledWindow 0x7f8fa3f4faa0 is mapped but visible child GtkScrollbar 0x7f8fa409c540 is not mapped

My versions from current Ubuntu 12.10 (with proposed, updates sources enabled)
ii evolution 3.6.2-0ubuntu0.1
ii libgtk-3-0:amd64 3.6.0-0ubuntu3.2

I tested totem and rhythmbox with overlay scrollbars removed (not only disabled) and this warning message is gone. Seems to be bug from gtk in combination with overlay scrollbars.
Therefore mark the bug for totem and rhythmbox invalid.

  [ Lars Uebernickel ]
  * Create native windows for the scrollbar overlay and tail As of gtk
    3.10, non-native windows are clipped to their widget's allocation.
    The hijacked scrollbar is given a 0-width or height when horizontal)
    allocation to make it disappear. Using native windows makes sure
    that the overlay and tail are drawn regardless.
