Bug #: 34360
           Summary: Text not rendered on buttons in spellbook in
                    CodeSpells
           Product: Wine
           Version: 1.7.0
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

To reproduce,
1) download and unzip 
fa110e7bfe7a3005bfb2aa0104be051c7fbd1a87  CodeSpells_Windows_Version.zip
from
https://sites.google.com/a/eng.ucsd.edu/codespells/home

2) Run it, accept the resolution, and wait ten seconds for the first grass
scene to be rendered

3) Click on the spellbook on the right

You should see a button on the lower left with text Copy,
and a button in the upper right with text Back.
On Wine, they are blank.

"winetricks corefonts" doesn't help.

This is a Unity3d game, fwiw.
