log

Debian 8 x64, kernel 3.16.7, wine-staging 1.9.17.
I run Steam with this command:
$ env PULSE_PROP="filter.want=echo-cancel" WINEARCH=win32
WINEPREFIX="/home/blob/.wineapps/skyrim/" /opt/wine-staging/bin/wine
"c:\Program Files\Steam\Steam.exe"

When I start Left 4 Dead and join game, I see corrupted ingame messages and
chat. Some words and parts of words were replaced with , and } (see attached
screenshot).
Last time I run this game (2 months ago) this bug does not exist.
Could this be fixed?
