glitch? Firefly helmet causing lag while harvesting bustables

[Korl]

As the title states, there seems to be a graphical glitch caused by the Firefly Helmet when worn while harvesting any bustable resource (Peblets, candies, etc) as well as when looking at certain walls that aren't part of the main ground (plastic objects on tables). 

Taking off the helmet solves the issue, but it's only a work around and the issue becomes tedious in dark areas or when harvesting at night.
