If we use the same approach currently implemented in notify-osd, we don't need to make any of the text in the dash adapt to the background, restrict anything or add even more logic in code. notify-osd does all its text-rendering with a centered and slightly blurred drop-shadow (white text against black drop-shadow). This makes sure there's always enough contrast for the text no matter what kind of background is used. See the attached sample for the technique implemented in notify-osd.
It may be a bit better than a solid, offset shadow, but if I simulate slightly worse vision by squinting or increasing the distance to 2 meters, the first example is bearable, only the 2nd is fine and the bottom 2 are just unreadable (as in really can't decipher).
And that is on uniform backgrounds ...Heck, even under normal conditions and given that rather large text size, the bottom 2 are unpleasant to look at.
