Using IntelliJ IDEA 15, I get these constant and annoying documentation popups whenever my mouse is anywhere in the code window for a decompiled class (from a 3rd party jar). It will popup docs for whatever variable/method/class/anything happens to be near my mouse. If my mouse is not near any lines of code, it will popup for the current classfile, so basically I can't browse code unless I move my mouse to another window.
It only happens with decompiled classes, not my normal code. How do I stop these?
Go to File>Settings>Editor>General - in the section 'Other', uncheck 'Show quick documentation on mouse move'.
In later versions of IntelliJ, the path is File>Settings>Editor>Code Editing, and it is under the "Quick Documentation" section.
