This is why some cc font size is too small.

OmniCC/core/timer.lua:42

self.charging = self.cooldown:GetDrawEdge()

better change to :

self.charging = not self.cooldown:GetDrawSwipe()

this is working, can we add this on the release?

come across this bug since BfA, only happens with ouf unitframe's aura
@warbaby 's solution works

This is the rule i'm using in the betas to determine if the cooldown is a charge one or not. It works for standard actions + libactionbutton buttons at the very least.

local parent = cooldown:GetParent()
if parent and parent.chargeCooldown == cooldown then
    return "charge"
end
