Every once in a while, the Zoho screen (when logged in only) turns into chaos and noise, like a bad old-school television set. This only happens on Zoho app, and only in some of them.

As example, it happens in CRM and in MarketingHub, but not in Desk or Projects. It also does not happen in any other web site or page that I've found. You switch to a different site and everything is fine, back to Zoho CRM and it goes crazy again. Even stranger, it only happens in the "data" portion of the screen. The menus are not affected (see screen shot).

Restarting the computer and/or the browser does not solve it. It goes away after some random amount of time - sometimes hours.

Attached is a screenshot of what it looks like when it happens.
