Gestures stop working after alert popup

I have 2 watchfaces installed on my F6Pro, which are designed to display additional information on gesture. They work fine normally, however what I am seeing is that if I get an alert popup displayed like the phone disconnection/connection then the watchfaces stop responding to gestures. It is as though the F6 stops reporting gestures after these alerts.

If it was just one watchface I'd think it was the watchface itself but for two to have the same behaviour makes me think it's an F6 issue

The only way I can get gestures working again is to press one of the watch buttons to access another function the go back to the watchface. I've also noticed that if I enable backlight on gesture then the issue doesn't seem to happen, though because of the battery hit from having the backlight activated in this way I really don't want to be using it.

Has anyone else witnessed this behaviour with their watchfaces?
