For all of those who now commented with "yes, nvidia here!" and similar: it would probably be more helpful both for you and others if you actually did downgrade to the version I mentioned and see if the problem persists.
If not: you got rid of the problem, people know what the cause is and they know a workaround until nvidia releases a new driver.
