Website spontaneously freezes in Chrome - how to debug?

I build this http://ipl.janstudt.de/ website which is supposed to run on the iPad (it does) and in Google Chrome. In Chrome (on Win 7 64bit), after a seemingly random time of a few minutes, the browser freezes. Also, sometimes when I click the "Reload Page" button in Chrome while on this site, the Browser also freezes. In both cases, the Browser recovers after 10-20 seconds.

How do I get to the bottom of this? There are no Javascript Errors. The memory footprint is very modest and does not increase over time (according to the he开发者_如何学编程ap snapshots). There are no plugins involved.

I really doubt it is your script; rather, I think it is Chrome doing something silly. I would test it on other similar systems to see if you can reproduce it. I've had it running on mine for about 5 minutes with no issues (Win7, 64bit, Chrome 5.0.375.127).

You could try to keep the profiler running and catch the freeze-up, but I think that would just be a waste of time.

Landed here while dealing with similar issue. Got a solution by changing hardware acceleration settings FYI: https://productforums.google.com/d/msg/chrome/daV0DhOXKVI/oBPZ6pUtBgAJ
