frame:Show() and frame:Hide() is causing fps drops

[zork]

I think the following is related to the texture memory issues, but I'm not sure.

On my compass castbar addon I experienced fps drops.

I changed the latency texture from Show/Hide to SetAlpha already. But Show/Hide on the castbar still causes fps drops.

If I comment out frame:Show() and frame:Hide() there is no fps drop at all.

I tried reparenting to a hidden frame and reparenting to UIParent when shown. Same fps drop.

Using SetAlpha on the frame works for me. No fps drops any more. Still super wierd.

How do you handle these fps drops?
