Thanks for the response, it did not fix the issue. I hope this doesn't sound condescending but did you follow the steps to reproduce? It's a weird behaviour which I think is related to window splits:

```
emacs -Q --daemon

echo "Test" > test.txt
emacsclient -c test.txt
C-x 3
C-x b *scratch*

# In new terminal
emacsclient -c test.txt

# I get a new window with the *scratch* buffer, but under Ubuntu 20.04 the first emacsclient instance is on top also
```

I think this problem was fixed in Emacs 27.1, so please upgrade and
try again.  If the problem persists, please tell the details.

(I couldn't reproduce this in Emacs 27, FTR.)

Thanks.
