Those look like some other cooldown timer, omnicc maybe, than the ones used by PitBull. If the buff/debuff icon is big enough some cooldown mods will display on the auras. I believe there is an option to suppress this behavior in Pitbull.
I believe the texture for bars is related to libsharedmedia-3. I had a few addons including Omen2 that only showed the Blizzard texture. I installed SharedMedia and SharedMediaLib at which point I had textures in ElkBuffBars and Omen2, I'm pretty sure I had them in Omen2. I'm not sure which of the two actually fixed the issue. Addons that were still using libsharedmedia-2 seemed to still give me texture options as before without SharedMedia installed.
