GI performance issue without lighting

I am developing a very, very simple 2D game. (2 drawcalls, 40 tris, 52 verts)
I don’t use any lightsource and i have deactivated everything at the lighting-window. (no lightmaps)
Running the game on a htc one s(Android), the profiler shows from time to time a peak caused by the GI.
EnlightenRuntimeManager.PostUpdate takes 10ms and more, resulting in a small, but noticeable lag.
Is there a way to get rid of this?

I think its a known problem:
Don’t konw when it will be fixed though :smiley:
