I know there were at least 3 problems caused by a Chrome update:
- Menu is not displayed correctly
- Mobile app is not responding to clicks
It is the OpenSource version of Chrome sharing the same code base but with no automatic update.
You can download it from here: https://sourceforge.net/projects/crportable/files/?source=navbar
I'm currently using Cromium 44.0.2383.0 and I no longer have to worry for a bad update.
