screenshot showing corruption; xfce+compton compositor.

Just upgraded from fedora 27->fedora 28 beta-ish; mostly seems fine; except
with the Compton compositor, where all of the xfce widgetry is a strange
orangey/red/corrupt; other windows (e.g. Firefox) seems fine.  f27 was fine as
well.
The attached screenshot shows the panel which is a boring grey; the icon to the
left is a red terminator terminal; and that speaker is black.

on f28 I have:
