Netbeans - Turn off - wavy red underlines - How?

Question

How can I turn off the wavy red underlines in Netbeans? I don\'t want to be interrupted while I\'m typing, and told that a half finished line of code is wrong.

This has actually already been addressed and illustrated in Arnold's answer to NetBeans. Disable error checking underline (+1); select Tools -> Options -> Fonts & Colors -> Syntax -> Category Error and adjust the font effects (or any other style) to your liking:

I've confirmed it to still work like so - please note that new settings won't have any effect until you trigger an editor update, e.g. by typing a letter.

Unfortunately this doesn't seem to help with performance in any immediately observable way (though removing font effects like this indeed used to speed up things in the olden days).
