Comment 1 for bug 1760661

So the deb package is also seemingly affected?

Does this happen with a specific web page/application open? In other words, if you close all tabs but one with e.g. http://example.org, do you still observe the lockups?

Can you open the chromium task manager with Shift+Esc and see if it gives any hints as to which process consumes an unexpected amount of CPU/memory ?
