More info - Workaround Found

Setup is Stellarmate OS running on RPi4 at the telescope as remote server. KStars/Ekos connected to Stellarmate from Linux Desktop via ethernet. Desktop Linux running Kstars/Ekos v  3.5.2 Stable. From Ekos CCD tab images downloaded from camera exposure sequences are displayed in the FITS viewer on Linux desktop. First downloaded image from camera displays HFR and Ecc values, but next image in sequence does not update HFR and Ecc values for the current image - they remain unchanged from the first image.

However, if I use FITS Viewer to load an existing image from a storage device, it opens in a new tab and displays the HFR and Ecc values correctly. Then if I click on the other tab from the camera image, the HFR and Ecc values update to the correct values. So the images displayed in FITS Viewer directly from the camera download are not updating HFR value but if recalled from a storage device HFR is displayed correctly.

This seems like a bug from how it worked in version 3.5.1.
