AltTab shows from main screen if used on secondary screen in an app with pop up window open

[kevinkuo0905]

Describe the bug

When a toast window appears within an app, e.g. download/browse for file prompt on a browser on non main display, AltTab pops up from the main display, showing its windows. I have AltTab set to show windows from separate screens.

Screenshots / video

Steps to reproduce the bug

1. Set up a main display and extended display
2. Open Safari or Chrome on extended display
3. Go to File -> Open File to create pop up window inside app
4. Try the AltTab command, it shows up on main screen

This happens on other apps with other pop up windows. Doesn't matter if it's set to show all windows or window from one screen only, it always shows up from main display. AltTab shows up correctly if no pop up window.

You say that your screens are set as extended display? Extended means that the 2 screens act like 2 large screen. In that case i think it's normal that AltTab shows all windows.

but maybe i don't understand your setup well. Could you film it to help me understand? Maybe film with your phone so i see the physical setup of the displays, then the logical setup, then a window that acts ok and a window that doesn't act ok.

Setup: left main, right secondary, alt tab only shows windows from the current screen

1. Alt tab works on main screen normally
2. Switch focus to chrome on right screen, alt tab works normally
3. Open a popup window in chrome, e.g. open file, alt tab shows up from the left screen and shows its windows, but I still have chrome on the right focused

This also happens on safari, and Microsoft word, as long as there is some pop up window in the app.
Hope this helps.

Thank you, the issue is clearer now.

You trigger AltTab from the secondary screen, while Chrome has a dialog open, and AltTab shows its UI on the main screen, weirdly.

You have set Show on: Active screen in Preferences > Appearance, correct?

Could you please try this build, and tell me if it helps?

Yes, show on active screen, and this build did fix chrome with 'open file' open, but still has the same problem on safari, microsoft word, powerpoint, etc.

Yes, it works correctly on every app I tested so far.
