Hi -

I have a few applets on my panel, such as weather, the notification area, cpu / net load, etc.  All of the icons and the background are just a black box.  The icons are there - I can mouse over them and click on them, but all I see is a black bar on my panel where the icons should be.

I also have a couple applets that are not blacked out: the XFCE menu, the Audio Mixer, and Orage (clock).

I'm running 4.14 on Gentoo.  I looked around for similar bugs and noticed some solutions suggested editting ~/.config/gtk-3.0/gtk.css, which I don't have.  Not sure if that's important or not.

I typically use the xfce-dawn theme.  I tried changing to others, such as Adwaita (since it has a gtk-3.0 directory in /usr/share/themes, in case that matters).  But no luck with other themes.
