Steps to reproduce the problem:
1. Open a new tab, open a new link, etc
2. Observe the mouse cursor shows the "working in background" cursor for several seconds

What is the expected behavior?
The mouse cursor should not change from the default pointer when opening new renderer processes.

What went wrong?
The mouse cursor shows the "working in background" busy cursor instead of remaining as the default pointer. This is visually very distracting, particularly when renderer processes are opening and closing without any user interaction. Even as I'm writing thus bug report my cursor has changed several times for no obvious reason.

Did this work before? Yes Chrome on Windows 7

This seems to only occur since upgrading to Windows 10. I've also tried disabling windows defender and any other background processes that might be interested in process creation with no success.
