Those ones :
They appear during code writing in case I’ve written the name of a method that is overloaded.
Those don’t seem to by inlay hints : I’ve disabled inlay hints about parameter names and types, and these hints still show up.
I know what method I want to use, I don’t need that frame that hides my code.
How can I disable them ?
>Solution :
You could disable it in the Settings | Editor | General | Code Completion | Show the parameter info popup in ... milliseconds.
