--- Comment #16 from Olivier F. R. Dierick o.dierick@piezo-forte.be --- Upgraded to Debian 9 "stretch" and the issue is NOT present with wine-staging 3.20 while it is still present under Debian 8 "Jessie".
So, I guess my issue is that current wine uses new features that are not provided by the Debian 8 libraries.
I advise anyone still affected by this bug to upgrade to a newer OS and retest.
