When in Legion areas as a druid with moonkin form (glyph of the stars) the game starts to lag. When moonkin form is off it runs perfectly fine. This also only seem to happen in Legion areas (Haven't tried MoP or WoD areas). It seem to start slowly and build up with time, after 5min-10min it is lagging really bad. I've narrowed it down to "elvui enhanced again". It gives no error message.
Also noted that the lag seem to disappear when I enter combat but starts back again when I leave combat.

I'm a level 120 balance druid, I noticed the issue when I was in Highmountain (Might only start happen here, not sure of that) during an invasion. It seems to happen regardless if i'm in a party or not. Warmode was on. With a bodyguard (Thisalee) and teleporting/loading screen seem to reset it (using the dalaran HS for example).

I have since stopped playing WoW so I have no idea if the issue persists, sorry

Do you still experience this issue?

No worries, then i'll just close this for now.
