I can't reproduce inside a poudriere jail. Try to...
- change Gtk theme if non-default
- check highlighting is visible in other Gtk3 apps e.g., gtk3-demo.
- about:support -> Refresh Firefox (or rename ~/.mozilla)
- various X11 driver settings e.g., DRI, AccelMethod
- disable compositing manager and use simple or no window manager.
- clear X resources e.g., xrdb /dev/null

Better ask on gnome@, x11@ lists or upstream. I don't touch widget code.
