Nine sliced textures in versions after and including 1.21.6 now cause significant fps drops.
This is likely due to them being split before rendering and each part be individually submitted, causing a single node to contain 100s to 1000s of elements just from a single sprite which then has to be checked through in GuiRenderState#findAppropriateNode when rendering subsequent elements.
I’ve attached a resource pack that when used in 1.21.5 will maintain your normal fps but when used in 1.21.6+ will drop your fps significantly.
Steps to reproduce:
Use the resource pack provided
Open the Social Interactions screen
Notice your FPS has dropped to an extremely low number
Open the game in 1.21.5 and apply the same resource pack and notice that your fps does not change
