memory usage screenshot

In Canvas with big count of elements memory reaches limit. It can be about 2GB. Unfortunately, I can't profile it, because dev tools fails. But in Chromium same canvas takes about 200mb. 
I found old tickets about the same problem, but they are not solved. This problem is critical for our product.
