--- Comment #3 from Artem S. Tashkinov t.artem@mailcity.com 2013-09-04 02:03:46 CDT --- One more revelation.
If I'm already running WinRAR with an English locale, and then run a Russian locale WinRAR - the latter uses a normal non-blurry font.
Anyways, I don't want locale to change my Wine's fonts!
