I have used Panorama X in Sierra and High Sierra, seems to work about the same in both versions. However, before going to High Sierra, I would try to fix Sierra. You can download the Sierra combo updater (https://support.apple.com/kb/DL1931?locale=en_US). Sometimes this will fix problems in the macOS. Also, you should try restarting into “Safe Boot” mode to clear caches. You do this by holding down the “Shift Key” at the startup chime until you see the progress bar. Then you have to login to the Mac, then do a “normal” Restart. If you have tried these things already, then please disregard, but if you have not these two steps are easy to do.
