Here’s a pattern I’ve observed:
Context
- There’s a
problematic application
. Determining which one is difficult; however, let’s say it’sCalendar
. - Desktop 11 has
Messages
; Desktop 12 hasCalendar
- Focus
Messages
- Focus
Calendar
(via hotkey, Cmd + Space search -> select application – however) - Focus
Messages
again (either directly, or with the shortcut setup forSwitch to previous space
- Desktop 11 (with
Messages
) briefly appears; it then quickly reverts to Desktop 12 withCalendar
- At this point, if
Calendar
is explicitly clicked and thenMessages
is focused OR Desktop 11 is switch to, the issue is gone
I’ve been struggling with this / trying to replicate it / trying to fix it ever since Catalina came out. I usually just logout/login (or restart); these steps are the first pattern I’ve been able to properly observe.
