The text of the values in the combobox dropdown list is white on
white. The *selected* item in the list is white on light grey, but all
the unselected items are invisible (white on white).
Which platform are you on, i.e. which operating system? I guess it is
Linux. In that case the default colors are read by Tk from the X11
options database, which is some cruft from the past to set options for
X11 applications. Try to run
xrdb -query
That should give you a list of default values, and maybe you can see
something. The dropdown list is actually a popdown menu, so look for
Menu colors. For instance, if you use a dark theme in your desktop
environment, it could be that the foreground is correctly set to white,
but the background is hardcoded white for some reason e.g.
