--- Comment #39 from Per Johansson per@morth.org 2012-10-22 04:42:11 CDT --- There are several workarounds mentioned in the comments, please read them.
IMO, easiest is to run winecfg, go to libraries, and mark dwrite as "native" or "disabled" Using steam.exe -disable-dwrite is also possible, but doesn't work when steam relaunches automatically or through the URL shortcuts.
