I just recently got the 190 update pushed. It mentioned lots of fixes. One was image handling.
I have found that now exiting an image is a bit slow or glitchy. A single gesture to go back does not exit and instead it needs two. Tapping an image instead still closes it but there is a delay that wasnt there before.
I’m on a pixel 7pro with gesture navigation.
I have the same, always need to double gesture to exit an image…
