Function definition popping up every time when opening bracket

[isavcic]

Hello,

Function definition is popping up every time when opening bracket like this:

Notice that this is a different popup than a regular mouseover definition popup (which I want to happen):

Is this a bug, and if not, is there any advice how to get rid of it?

Thanks

Thats called "Signature Help" or "Parameter Hints"
Its helpful when the function in question has multiple parameters.
As you type the parameter, the underline moves to the current parameter.

You can disable this by setting "editor.parameterHints": false

Thank you for the explanation! Any way to change font size of it?

Not at the moment. There is an open issue in vscode tracking that. You can add your upvotes/comments there microsoft/vscode#13480
