Garbled display when using ZOHO CRM

Garbled display when using ZOHO CRM

For some reason, periodically, whnI try to access ZOHO CRM with Chrome I get a garbled display. See attachment.  It looks like data from within my CRM is visible. How do I fix this.  I get the same behaior from my PC and my laptop,  When I switch to incognito mode, it seems to go away.
