SUMMARY
If I choose to mirror the laptop display to an external one, the 'present
windows' desktop effect shows no windows. However, I can still switch windows
using Alt+Tab.
STEPS TO REPRODUCE
1. Connect an external monitor

display options

screen edge)
OBSERVED RESULT
No windows are shown, just an empty desktop

Windows should be shown in the 'present windows' effect
