--- Comment #5 from Daniel Kamil Kozar dkk089@gmail.com --- Thank you very much, RĂ©mi.
I applied the patch on top of master (5942da6c6ca) and I'm very happy to report that WINEDEBUG=+no_size,+no_flush makes the game work normally again. I tested all combinations for completeness and WINEDEBUG=+no_size works okay too.
