I installed Antergos in Virtualbox. The host OS is Arch Linux. I found whenever the terminal is opened, either from the dock or from the panel activated by the nine dots button, the terminal window doesn’t have focus. This seems to happen only to the terminal. The browser gets focus as expected.
~$ uname -r 5.0.2-arch1-1-ARCH ~$ cat /etc/issue Antergos Linux \r (\l)
