Preventing fade on loss of focus?

[Mark Farver <mfarver mindbent org>]

I am using GTK3 with Weston/Wayland and when I play a video using
gstreamer my main window loses focus and all the labels dim.  This is
not the behavior I want since the video is part of the window.  This
is an ATM like kiosk, so there is no user interface issues related to
the loss of focus.

Is there a way to modify the window system to disable the dimming
feature, or set the focus/unfocused styles the same?

Thank you
