It sounds like this is some interaction with the recent change to allow
Vim to receive events from the terminal when focus is gained/lost. This
is described in ":help xterm-focus-event".
The terminal sends <Esc>[I when focus comes back, which is what makes
you leave insert mode (<Esc>) and show that popup ([I).
If this were working correctly, you wouldn't have noticed a difference
(as is the case in xterm), but there's something going on with the other
terminals.
Can you provide the package names and versions for the terminals that
aren't working right?
Also, it would help if you ran the below command in each terminal
(replacing <term> with the terminal name) and attached the resulting log
for each.
vim --cmd 'au FocusGained * call ch_log("f_in")' --cmd 'au FocusLost * call
ch_log("f_out")' --cmd 'call ch_logfile("focus_<term>.log", "a")'
In each terminal, once Vim starts please switch to another application,
back to the terminal, and then exit Vim. That will capture the terminal
codes that Vim sends and the responses from the terminal so we can try
and figure out where things are going wrong.

You can add the below snippet to your vimrc to disable this
functionality:
if exists('+t_fd')
set t_fd=
set t_fe=
endif
