Language Spell Check

How do I remove Spell Check (red underline on words) when I’m typing using Bahasa Indonesia or any other languages?

Please help me solve this. Thank You.

To answer this question, it is important to know which application is used. (In Libreoffice this can be switched on/off with shift+F7)

It’s happened on some apps that I’ve tried including: LibreOffice, Brave, Obsidian, What’sApp, Telegram, and other.

I need a solution that fix this problem in the entire system, not only in some apps with different config.

Maybe this will help your search: How To: Enable Spell Check System Wide?

Maybe it’ll help you shut it down. Where necessary, I always adjust this in the application, applicable.
