Created attachment 49241 [details] WINEDEBUG=+winsock output
I see 3 TCP sockets, all connecting to the same address. It looks like only one of them is used most of the time, the other 2 very rarely do something. You are using overlapped structures but without callbacks so I think I should see calls to WSAGetOverlappedResult but there are none, there is probably other way to receive overlapped data that I'm not aware of.
This bug may be true as long as bug 36662 still exists. That bug shows some leaks we could not find yet.
You should fix your wine: err:wincodecs:PngEncoder_CreateInstance Trying to save PNG picture, but PNG support is not compiled in.
