Really liking the new image settings such as not showing the controls by default. But they kept appearing for me and I couldn’t work out why until just now.

Open an image, zoom in, then pan a small amount. Looks like a small drag is interpreted as a tap, and the controls alternately show / hide.

I’d happily turn the overlay off completely if that was an option; I can’t remember the last time I actually needed them—the close icon isn’t needed with the swipe to dismiss, and you can easily get to save / share by long press after closing. Since I use those so rarely, that would be better UX for me.
