Hi, in my experience with masking in wow it doesn't..... some code I just tested using a mask created in gimp that turns any texture in to a circle works fine.

local tex = Frame:CreateTexture(nil, "ARTWORK", nil, 0);
	tex:SetTexture(some texture);
	tex:SetAllPoints(Frame);
	tex:SetMask(Some Path to CircularMask.tga")
