--- Comment #4 from Anastasius Focht <focht at gmx.net> ---
Hello folks,

haven't see this in a while, although the code hasn't changed so the problem is
potentially still present.

https://source.winehq.org/git/wine.git/history/HEAD:/programs/winemenubuilder/winemenubuilder.c

https://source.winehq.org/git/wine.git/history/HEAD:/programs/wineboot/wineboot.c

I've tried to reproduce with a small script that switches between different
versions before triggering WINEPREFIX updates. Using 'inotify' tool to
capture/watch the updates in real time but no avail. Tried with clean
WINEPREFIX and a more "heavyweight" one with .NET Framework 2.0 and 4.0
installed.

'prefix_update_test.sh'

#!/bin/bash

update_prefix()
{
  version=$1
  (
    export
PATH=/home/focht/projects/wine/mainline-install-$version-x86_64/bin:$PATH
    echo "### triggering prefix update with Wine version $version ###"
    # process starts: add +timestamp,+process
    WINEDEBUG=-all, wineboot -u && wineserver -w
  )
}

let i=0
while :; do
  let i++
  dt=$(date '+%F %T')
  echo -e "\n### $dt loop iteration $i ###"
  update_prefix "1.7.43"
  update_prefix "3.14"
  update_prefix "2.15"
  update_prefix "4.3"
done

If you still encounter it, you might reopen. In that case please provide some
more details, i.e. old Wine version (if you remember it), current Wine version,
any specifics to the WINEPREFIX that was updated etc.

$ wine --version
wine-4.4-1-gc29bababef
