--- Comment #4 from blog@pozimski.eu --- Created attachment 55680 --> https://bugs.winehq.org/attachment.cgi?id=55680 Sins of a Solar Empire: Rebellion launched with wine 1.8.4
Thanks, that indeed seems to be the case. The game ships a copy of the native d3dx9_36.dll which is loaded with wine 1.8.4 from Debian backports. I attached the full log run with "WINEDEBUG=+loaddll".
