Vuhdo options -> general -> indicators: I chose "Background: Solid" from the bar background drop down menu and "Health (generic, class col) from the health bar drop down menu. Unfortunately this did not change it.
I also ticked "Invert" (next to Health Bar) to see if that would help. That only changes the way the health bar works as the little tooltip for it mentioned. I noticed that when I heal myself, my bar will suddenly turn white as if there is a "show class color when healing" option(?). This only happens when I click on the bar and use a heal set in Vuhdo (right button greater heal/middle flash heal).
Does anyone know what I might have missed? It drives me bonkers..
