I've run into something similar to this a few years ago where chrome randomly introduced a rendering bug that resulted in a similar crash and only affected our application in seemingly random fashion. I don't remember the full context but I think it was something involving layers & transparency.

We finally figured it out when a coworker couldn't replicate and we noticed they were a version of chrome behind. We were able to track down the specific commits in chrome that broke & fixed it in our case which was pretty cool to see at the time.

If you have any more time I recommend reading through the commit log and see if you can find the changes that broke/fixed this for you. I'd bet on another rendering bug.
