> Please, run a regression test:

It is definitely a good idea, but Wine is a quite big project (which building
takes time) and I would leave it as the last resort to bisect it.

I will try to test it with 5.8 to limit number of options, but maybe some of
the developers could suggest a suspected, related commit(s)?

Testing 661 commits [1], even with 0(log n) complexity of bisect, would take
"some time", looking at the Wine building time.
