Yes, it doesn't make a difference and -Q doesn't, too.  Here's what I
did:

1. Start the server within gdb

   $ gdb /usr/bin/emacs
   (gdb) run -q -nw -f server-start

2. Connect with a X11 client

   $ emacsclient

3. Close the frame with

   C-x 5 0

it doesn't vanish but it won't be repainted anymore.

4. Halt the server process to get a backtrace.

   $ killall -sSIGSTOP emacs

and in gdb

   (gdb) bt full
