Alt-Tab raises all windows of an app (when using multiple monitors)

[Juan Carlos]

Hello,

I'm getting the same behavior as the link below, in Ubuntu 18.04 you could do a quick alt+tab to change to the first window of an application, but now that I updated it to the latest version (20.04) I have the all windows of an app that are displayed with Alt+tab.

This was supposedly fixed by Didier Roche, check out the following link https://bugzilla.gnome.org/show_bug.cgi?id=786009.

The behavior is best described in the videos made by Didier:

I can't seem to reproduce the issue on Ubuntu 20.04. Can you please try removing this extension:

  Current_screen_only_for_Alternate_Tab

and tell us if that makes a difference?

Hello, I dont know why that extension shows as installed, it was already erased when i posted the bug.

So removing it changed nothing.

gsettings get org.gnome.shell enabled-extensions:

['touchpad-indicator@orangeshirt', '<email address hidden>', '<email address hidden>', '<email address hidden>']

Thanks

Hello, Ive realized something, this behavior only occurs when I'm using a second monitor, if I alt tab with only 1 monitor then alt tab works as intended, but when using a second monitor then all the windows of the app that are in the second monitor are displayed with Alt+tab. This wasn't the case with Ubuntu 18.04.

Thanks.
