Text in WPF application appears unreadable or does not appear at all under VMWare

I've got a user running my WPF app on a Mac with VMWare, In Win 7, and most of the text in the app is unreadable. I've ran this on my own VMWare-MacBook pro setup, and it seems to be fine. Here's a screenshot from the user:

Any idea what the cause might be?

When we had this and other issues with some of our test staff, it was because they had the memory settings turned too low for the video emulation to handle WPF. VMWare defaults to somewhere around 256 MB for total RAM for the guest OS. Try turning that up to 2 GB or higher. You can also tinker with the video settings for the VM. In addition, check the font size and DPI settings on the guest OS.

Update to the latest VMWare Workstation software and install the latest VMWare tools. There was a version of 7.0.x that had this issue. In our case you couldn't see the text at all.

My VMWare version: 7.1.4 OS: Windows 7 x86

Had the same issue, the solution for me was to update the WMVare Tools to the latest version (as of today). (VMware Tools version 8.4.6)
