Issue Details

When using TestStand 2021 SP1 Message Popup with Display Image option, there is about a 2 second delay before the image appears on the popup window even if the image is small. 

Solution

This behavior is expected. It is due to a change in the technology used to implement the message dialog. In versions prior to NI TestStand 2021, the message dialog was using Internet Explorer. As it is EOL and no longer supported by Microsoft, the Msgbox step type was changed to Chromium Embedded Framework (CEF) rather than Internet Explorer (IE). As CEF is slower than IE implementation that is why we see this behavior.
