I have a super annoying heisenbug, that never occurs during the Chrome debugger performance recording session. Basically it's an Angular/AngularJS hybrid app with a form that freezes when you return to it after navigating to another tab.
Any suggestions on how to debug this other than just commenting out code step-by-step?
Slash dependencies and code until you get to a state that doesn't freeze. Then start adding dependencies and code back one at a time until it starts freezing again.
Narrow it down and you'll get it, eventually.
