Preview in home app (iOS and macOS) constantly updates
This started happening in the past few days, and starts off mild but gets gradually worse.

I have two foscam cameras which I’ve been using successfully with Homebridge camera.ui, set up for HSV.

A few days ago, I started to notice the countdown on the camera previews started to act weird. Instead of resetting to 0, and then counting to 1 sec ago, 2 sec ago, etc. it would update the image and then immediately go to like 5 sec to go, 6 sec to go, etc.

Today, I noticed that this disparity has gotten so severe that the previews constantly update, and starts the count at 10 secs to go each time. This causes the preview to wink in and out constantly in the Home Screen preview.

I’ve tried rebooting my raspberry pie that hosts my homebridge and camera.ui. I’ve also tried removing and adding both cameras from HomeKit.
