You have been subscribed to a public bug: Sections of certain windows will be incorrectly rendered as black when they should be rendered as the default color according to the selected theme.
Although I'm not 100% certain, I've tagged this as a lightdm bug because I tested various configurations of nouvea/nvidia and unity/gnome-shell and found this happened in all configurations. To clarify, I tested this in the following configurations: nouveau + unity nouveau + gnome-shell nvidia-340 + unity nvidia-340 + gnome-shell and found this happened in several windows, notable gedit and gnome- tweak-tool (only gnome-shell). In general, it seemed to occur in the sections of the window that are otherwise empty and not populated by widgets.
