--- Comment #2 from Zebediah Figura z.figura12@gmail.com --- In general, a sufficiently determined process can certainly cause high CPU usage in wineserver, yes. That's not really a bug per se.
However, if the aforementioned commit is to blame, that probably means we're polling a fd and not doing anything about the fact that it's signaled, which is a bug. Can you please attach a log with WINEDEBUG=+pid,+server,+winsock,+seh,+timestamp? Ideally with wine 6.11, which has a few tweaks to the way sockets are polled.
