Output of WINEDEBUG=trace+winmm wine euphoria.exe
If any controllers are plugged in, approximately every second Euphoria will
freeze for a brief moment.
Euphoria is a Visual Novel made by Clockup. Be warned, it's (very) NSFW. I'm
using the English release by MangaGamer: https://mangagamer.org/euphoria/
The problem affects other games by Clockup. They likely run on the same engine,
since the file structure is very similar.
This wasn't a problem with older versions of wine, git bisect points to
4f1095a0ee4c7577e5287e56e388c36d0ba659ad — winmm: Reimplement joystick APIs on
top of dinput, by Rémi Bernon.
Since this started after a winmm change, I ran the game with
WINEDEBUG=trace+winmm, the log is attached. Looks like find_joysticks is
regularly called, the game freezes at the same time these calls are logged.
My guess is that find_joysticks is slow for some reason, so it blocks the game.
The more controllers are plugged in simultaneously, the longer it freezes for
(I tested with 0, 1 and 4).
The game doesn't freeze on my Windows 10 install at all, even with 4
controllers plugged in.
