Hi,

This happened during the Sonoma beta a while ago, then Apple fixed it. Are you on the public release or some beta version?

Thank you

I am on the public release.

I was able to reproduce it on macOS v14.1.1.

I can't reproduce it with Chrome, but I can with Terminal. I expected that either every app has the issue, or none has the issue, since this indicator is an OS-level UI element.

Was able to reproduce it on:

• terminal
• Firefox
• Google Chrome
• Slack
• vscode

For me the bug looks quite consistent.

I tried to debug the window, to see if there is anything we could use to filter it out. As I did this, I stopped being able to reproduce the issue, with any app.

When the issue stopped happening, I could see that this blue-indicator window has level == 3, which is the backstopMenu level.

I suspect that sometimes, the OS puts this popup on the wrong level, and this is when AltTab shows it. Then it gets fixed doing something, like changing window focus or something else, and then AltTab stops showing it.

AltTab is most likely doing its job at reporting windows, and the OS is sometimes rendering these on the wrong level, which makes it show in AltTab.

Not sure what we can do here to mitigate this.
