Rebooted ROCK and it is still happening - every page refreshes every 3-5 seconds. Seems Ok on my Android phone app so it doesn’t seem to be a ROCK issue.
This may be related/similar, but it is not the same environment. I had this issue on my Windows 11 laptop Remote last week (Core is a 2019 MBPro), and had to update my Windows laptop’s video drivers (NVIDIA) which solved the issue. Are you running MacOS 13.1? That may address the issue for you as the drivers are all embedded in Apple’s OS updates.
