Recent wine binaries caused lots of logging to syslog

[fiddlesticks]

running Roon using wine very happily for a while (Linux Mint 21.1)
Recently Roon wouldn't start, and complained about old versions

So I upgraded to wine-staging (8.0) - and then Roon started, but logged an enormous amount to syslog (like >20Gb in 2 hours)

eg:

May 28 00:08:14 blackcat wine-Programs-Roon.desktop[5070]: 0118:fixme:ntdll:RtlGetCurrentProcessorNumberEx (000000000029DCB8) :semi-stub May 28 00:08:14 blackcat wine-Programs-Roon.desktop[5070]: 0118:fixme:manipulation:update_manager_Update 0000000001069D50, 0000000000000000

(etc etc)

grep Roon syslog | wc
165989743 1465657893 23857530414

I tracked the problem down in the end and changed the beginning debug incantation in start_my_roon_instance from WINEDEBUG=fixme-all to WINEDEBUG=-all

so it ended as

env WINEPREFIX=/home/$username/my_roon_instance WINEDEBUG=-all wine /home/$username/my_roon_instance/dosdevices/c:/users/$username/AppData/Local/Roon/App

And now it's running fine and syslog is as it should be - 80k or so.

Hope this helps anyone else with the same problem
