I cannot reproduce this.  But my Git for Windows is quite old, so
maybe newer versions made some change?  What is gitk on your machine?
Is it a gitk.exe program or some kind of script?

gitk is a GUI program, so why are you invoking it with
call-process-region?  gitk will never read anything from its stdin or
write anything to its stdout.  I suggest to invoke gitk from Emacs
like this:

  M-! gitk & RET

IOW, add the "&" character at the end of the command line to make the
invocation asynchronous, instead of letting Emacs block until gitk
exits.
