-moz-field is transparent on Ubuntu 16
[Tracking Requested - why for this release]:
All arrow panels are affected as well, and a closer look reveals that the location bar and search bar themselves (not just their autocomplete popups) don't have a white background anymore either. Basically, it looks like -moz-field is now transparent.
Summary: Autocomplete popups are transparent → -moz-field is transparent on Ubuntu 16.10
Thank you for the patch :)
Prior to GTK 3.20, or more specifically https://git.gnome.org/browse/gtk+/commit/?id=580ea227a6bb19ad6c6d4766b3a36dbad24583f3 the background of each window, even non-native windows, would be cleared before each paint with operator source. https://git.gnome.org/browse/gtk+/tree/gtk/gtkwidget.c?id=402cecf9a2aecf95ac8efca84179adcb1ce8e956#n7102 Windows are created with a transparent background pattern by default https://git.gnome.org/browse/gtk+/tree/gdk/gdkwindow.c?id=402cecf9a2aecf95ac8efca84179adcb1ce8e956#n1401 That meant that windows would occlude any content behind them, and themes needed to set backgrounds for the windows so that they were not black. Since the change, the background is no longer cleared and so content behind the windows is visible. Ambiance for 3.20 does not set a background on the text node of the textview, but only on the root node of the textview. Gecko can no longer depend on the text node having a background, but needs to also consider the root node background. Prior to changes that landed for bug 1320860 and bug 1322120, and now, with those reverted, Gecko happens to pick up Ambiance's style rule for the textview root node because the style context used has not yet been adjusted to conform to GTK 3.20's text node.
