unaccounted time between mesh update and render update

Hello, as the title says I am getting the message “unaccounted time between MeshSkinning.Update and ReflectionProbes.Update” under CPU in the profiler. I am developing a VR game and this is a huge issue for me as every few seconds I get a frame drop down to 30fps which is a huge problem for VR. It’s usually in the profiler hanging at around 10% but occasionally jumps to 30-50%.

Is this a problem or am I missing something?

Same problem here… Unity 5.5.4, Win 8.1 pro
