git gui menu fonts are too small, unreadable

git gui menu fonts are too small, unreadable

Menu fonts in 'git gui' are too small to be readable
(only one or two pixels high).   "gitk" works fine.

Same result whether I start 'git gui' from the command line
or from gitk.

I'm running cygwin 32 on windows 7.   uname -a shows:
CYGWIN_NT-6.1-WOW myname-LT 2.5.1(0.297/5/3) 2016-04-21 22:12 i686 Cygwin

Starting the X server from tcsh as:
  setenv DISPLAY :0; run xwin -multiwindow
(starting the server in foreground so I can see any 
console messages)

After the flurry of messages from X server initialization,
there is no output to the console or to /var/log/xwin/Xorg.0.log
when starting git gui except one line to the console:

  OS has icon alpha channel support: yes

So far I have tried:
  Searching mailing list archives
  google.  Lots of google...
  installing any missing xorg-X11-fonts-* packages
  re-installing git, git gui, gitk

cygcheck.out is attached with usernames redacted.

Any ideas are welcome.
Thanks and Best Regards,

Thanks for reporting this problem.

I was able to reproduce this problem, with a fresh installation, but 
only on x86, not on x86_64

It seems that default font used by git gui is '0pt DejaVu Sans', where 
0pt has a special meaning in Tcl/Tk of 'a platform-dependent default 
size' [1], which is 12 pt for on X11.

There seems to be a bug somewhere in Tcl/Tk (or perhaps in the 'git gui' 
script), so that on x86, the size attribute it ends asking fontconfig 
for is INT_MIN, not 0.

It also seems that fontconfig has recently changed it the way it handles 
this invalid value, now giving you a very tiny font.

Until we have a solution, you can work around this by setting the font 
to have a definite size in ~/.gitconfig, e.g. adding

> [gui]
>         fontui = -family \"DejaVu Sans\" -size 12 -weight normal -slant roman -underline 0 -overstrike 0
