Eterm has in its manpage said that --font-fx would allow the user to control the effect that Eterm does to the text that it outputs to its window.

But if that were the problem, I think there shouldn't be any effects at all, i.e. even the black bottom-right shadow shouldn't work.

I accidentally stumbled in my trials upon a switch that made the black bottom-right shadow disappear, but still could not find anything to change its color, direction, or make it into an emboss, outline or anything else.
from the manpage: --font-fx effects Specifies the effects to apply to the terminal window font. The value of effects is a single string containing a series of corner/color pairs. $ Eterm --font-fx "bottom_right white" $ Eterm --font-fx "emboss white black" ...
