Happens both in and out of cognito mode.

OS: Yosemite

The event log is pretty short.

I am seeing the same behavior as of today.  If I switch to another Mac user, Chrome Canary works, but all Chrome pages are blank in Canary on my normal Mac account.

I've tried different chrome users as well as incognito mode, but that does not help.

I was able to recover by deleting this directory:

/Users/<user>/Library/Application Support/Google/Chrome\ Canary

This morning it was working fine.
Then I made an update of Google Chrome Canary this morning and since this update I encountered the behavior of white pages... 

Same issue here today after auto upgrade. But no log outputted.

This looks similar to the  bug 603452 .Hence merging this into 603452.

Please feel free to undupe if not the case.

Thanks,

yep kavvaru, thank you for merging, it was similar to 603452.
i just quit and start Chrome Canary 5 minutes ago and I confirm it works for me now, Version 52.0.2709.0 canary (64-bit)
thank you all :)
