[435] Equip/Unequip items in the inventory causes microstutter and weapon set flickering

[Sensuki]

 

This video demonstrates that equipping and unequipping items on characters often drops the frame rate down very low / microstutters the game, and causes the character's weapon set visible on the avatar to flicker.

Expected Result: equipping/unequipping shouldn't cause such a performance loss, and changing items should not make the weapon set flicker.
