ALT+Tab does not show all open windows

Since i upgrade to Ubuntu 21.10, when i press ALT+TAB to switch the window with focus, it does not show all open windows. I have 2 monitors. I already made apt update e apt upgrade and reboot the computer but the problem remains. I did not find a reason for missing some windows. When i press ALT it shows all open windows but the same missing windows appear in a second box in the top:On the dock menu,all windows appear open (and this is currently the way i can go to the missing open window).

Any clues to fix this? Thank you.

I made a screen video to show the problem:screencast video of possible ubuntu error
