FPS Drop with big amount of Enchanted Items/Potions placed in Item Frames

Basically whenever I look to a place with a big amount of Enchanted Items and/or Potions placed in Item Frames, my Frame Rate drops a lot [Screenshot_1]. It's not caused by the big amount of frames since if I'm looking somewhere else with a big amount of Item Frames with or without Items in them, or I'm just simply looking somewhere else, the FPS don't drop [Screenshot_2]. This is not a duplicate of the FPS drop when charging a Bow since whenever I do it it doesn't drop the FPS.
