so what should i so?

Answer 1

If you are using neovim there is an option called :h pumblend which can be used to change the transparency of the popup menu.
Are you sure gruvbox caused your vim to lose transparency? I am not sure if vim is able to change a terminal emulator's transparency. I or someone else might be able to advise you better if you post pictures of what has changed.
