My user is running latest release of SmarterMail v16 and is having a display issue with larger folders in webmail. When loading his Archive-Inbox folder (25,000+ messages) the message list will go blank at some point while scrolling through the list. Screenshot can be found here: https://pasteboard.co/HqPtgdB.png

 

I have not been able to replicate the issue in Chrome/Firefox/etc, only in Internet Explorer/Microsoft Edge. Is this an IE issue, or something that can be resolved on the SmarterMail side?
