Try the following:

(start-process-shell-command "1" nil "emacsclient -c ~/.bashrc")
(let ((process-connection-type nil))
  (start-process-shell-command "1" nil "emacsclient -c ~/.bashrc"))

The second command will cause flickering, though opens the file in the
same frame (not the new as one would expect from -c switch).

To reproduce what I am seeing, you may need to adjust xdg- database
adding the following .desktop file:

[Desktop Entry]
Name=Emacs Client
Exec=emacsclient -c %f

Then, make sure that xdg-open uses the desktop file for
application/x-shellscript (xdg-mime query default

Finally, run 

(start-process-shell-command "1" nil "xdg-open -c ~/.bashrc")
(let ((process-connection-type nil))
  (start-process-shell-command "1" nil "xdg-open -c ~/.bashrc"))

Observe flickering + Emacs not opening the file.

Which function are you referring to?
