--- Comment #7 from Ricard Wanderlöf ricard2015@butoba.net --- If dwrite is the problem, should it work with -no-dwrite appended to the wine command line (I tried it and it made no difference whatsoever).
BTW, if it's of any use, when testing it I reinstalled both wine and Spectre several times, and the font rendering distorsions were sligthly different every time, sometimes being unnoticable, and sometimes being fairly severe.
