Can you do a regression test to find out which commit broke it? See https://wiki.winehq.org/Regression_Testing
I feared that you would ask that and was hoping someone would recognize the affected code paths. ;) I'm using Gentoo and I'll see if I can figure out how to use its package system to build Wine from a local copy of the git repository. For now I'm fine with 7.7 and perhaps someone else runs into this before I master the regression test. :)
