Ask HN: Web app freezes, but not when Chrome is recording. How to debug?
6•febed•3mo ago
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?

If you can't inspect it due to it freezing, I suggest trying to make it not freeze to begin with.
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.

How many machines have you tried? This sounds like it might be one of those things that only happens on a dev box.
