Good evening, I found a way to create a head that can cause a crash or lag.

This head uses high resolution texture, that causes a crash or lags when rendering it

To reproduce:

• Upload a texture with a size of 12000x12000 pixels (Tested with education.minecraft.net notes)
• Encode our link with json in base64

{{{"textures":{"SKIN":{{{"url":"Picture url"}}}}}}}

• Create a head with the NBT:

{SkullOwner:{Id:"70adb5ca-01f3-4d11-b7b7-6d273e14cc9d",Properties:{textures:[{{{Value:"Hash, that we get from 2th paragraph"}}}]},Name:"any name, that you want"}}

P.S: Also we can use random uuid.

One of ways to fix this is - *limit the size of the textures.

I apologize if there are spelling mistakes somewhere, i don't speak english good.
