Apparently, I made a mistake with my version numbers. I retested with 0.9.47 and successfully reproduced the bug. I also retested with 0.9.46, and could not reproduce the bug. For the record, I ran my regression test from current Git back to 0.9.45, so the first commit I mentioned should be the same as if I had run the test from 0.9.46 to 0.9.47.
That along with your comment that native Tahoma fixes the problem suggests that Tahoma replacement in Wine lacks some glyphs needed for this application.
Could you try to figure that out either by comparing screen shots or with a +font,+xrender log?
