I have 2 Tellmewhen icon trackers setup to track my MH and OH weapon imbues (enhance shaman).

I have them setup to only appear + play a sound when the imbues fall off, but every minute or so they both flicker on and off very quickly, like just a small flash of both icons.

Anyone else ever experienced this? It seems to happen only with the weapon enchant icons I have, none of the other types do this.
