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.
