it also leaks the audio of tabs before logging in.

Even though I had disabled all 'restore' applications features, macos sometimes decides to 'start' browsers BEFORE logging in after a restart AND those start auto-playing audio from whatever was paused before the reboot (or many days before).

Since then I went rather deep disabling that feature, but I never trusted it.

Somewhat loosely related, but I have something similar with the iPhone browser. Where opening the browser will shortly show the last page I had open (even I carefully closed it before closing the browser). Even if it never got me into trouble, I found that annoying as s. And could potentially make problems.

FWIW, what you’re seeing is likely just the cached thumbnail that iOS creates for the app-switcher UI, not an interactive web session.

Yes, but still if you have somebody looking over your shoulder, it can leak whatever you've been looking at.

There's a way to block that entirely for "secure' apps, but iOS could be smarter about this, and cache some stripped down view or expire that cache quicker.

This is also the case for FaceTime; The last image the camera captured will stay visible in the app switcher like forever... so other people who use your iPad / iPhone can see it.

Yes. Something like that, but can reveal a lot of the site you were in.
