Strange icon display when rotating through report URLs

[FredTheFrog]

Using a PowerShell script to drive IE11 on Windows 10.  The script rotates through seven or more PowerBI report URLs in fullscreen/chromeless mode.  It works nicely, EXCEPT for when THIS screen appears.  Anyone seen this one, before?

Hi @FredTheFrog,

It seems they are from the place as the snapshot shows.

Did it appear as a report? How did you do this?

Best Regards,

I made changes to the PowerShell script yesterday, to quit and restart the Internet Explorer instance every 'n' iterations of the loop.  It seems to have resolved this issue.  My guess is that IE's cache of some underlying JavaScript is being corrupted, causing the strange display from Power BI.  FYI, yes, this did appear when attempting to display a Power BI Report URL.
