i don't mean classtimers below the playerframe, i'm talking about the buff icons below the targetframe :)
I'm pretty sure those unitframes are oUF with a custom layout, so the skin on the target's debuff icons would be whatever texture that person defined as the buffborder texture for oUF within their layout.
On another note, it seems like CaithUI 10.5 has decreased my FPS by a HUGE amount. My AV group was attacking Drek and I was running at 60 FPS the whole time. Now that I have CaithUI 10.5, while we we're attacking Drek my FPS dropped down to 10-20. It seems to be a bit skippy in the main cities as well now to. Could it be memory usage of the UI? or maybe I just need to update a few addons seeing as I had this problem before with previous addons that dropped my FPS until I updated them. From what I've read on other forums no one else seems to have this problem, so any help would be great.
It means that one of your addons wants to use AceGUI-3.0, but its author failed to correctly embed this library. Read the error more closely to determine which addon is actually complaining, and then ask its author to fix its embeds.
