Some custom debuffs;
Lingering Corruption on Vectis
Annihilation on Mythrax
Putrid Blood on G'huun
These debuffs usualy are on all raid members with stacks during the fights. So i prefer not to color them by unticking "Bar Color" option in their custom debuff settings.So i can still track who gets how much stacks with the icon on the bottom-left side of the frame and for a cleaner look.
This used to work till 188.8.131.52.
Since 184.108.40.206 unticking "Bar Color" option of the respecting debuff won't do its job.
