automatic screen refreshes cause my screen to change position


When viewing my portfolio in the "Holdings" tab, every time the screen/advertisements refresh the screen shifts off of what I was looking at.  This happens constantly every 30 seconds or so and is hugely annoying.  Why would anyone pay for this?  I'm running on Chrome v80 on Linux (Fedora 31).  Any help would be greatly appreciated and might get you a customer...  :-)

I like what the site has to offer, but this issue is beyond anoying.
