I have the same problem, with the templateCache push

I also have the same problem. In my case, I have a component repeating for each item from the data that I use. After scrolling down and up, some drawn components are wrong. I debugged changes caught by ngOnChanges and the data passed to the component after scrolling up is wrong.
