There is:
No fix
No effect on performance
This affects:
All users
All Chrome versions
This is not the first time this bug has occurred.
Happened in 10.9 as well.
Also IIRC this affects most web apps including I believe Safari. Something related to Activity not getting a response from processes without a Window or something of the like.
