Things like the picture provided would happen on versions 1.17 and up(has happened to all upper versions) where items in my inventory or hotbar would dissapear and create a bunch of colorful static on the screen, this also happens to named villagers and mobs, making it difficult to play on servers like hypixel. But whats strange is it doesnt affect version 1.16.5 and lower. Im not sure if its just a really bad computer I have or its a bug, thank you!
