I'm not sure how to consistently repro this but once it started happening it continued to happen many times. I'm fairly certain this is new behavior in M51.

What steps will reproduce the problem?
(1) Open lots of tabs and applications.

What is the expected output?
Nothing special.

What do you see instead?
The entire display started flashing black for about half a second and then coming back. This repeated several times and eventually stopped happening. No state was lost in chrome so it would seem that chrome was not crashing but perhaps the gpu process was? I have filed feedback as well
