Bug ID: 42140 Summary: "Unrecognized stencil op 0" messages flooding system log in Söldner Secret Wars Product: Wine Version: 2.0-rc2 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: minor Priority: P2 Component: directx-d3d Assignee: wine-bugs@winehq.org Reporter: max.kue@gmx.de Distribution: ---
When playing Söldner Secret Wars - Community Edition (free (as in beer) download http://www.soldnersecretwars.de/main.php?page=download&lang=en) tons of log messages are generated. The game itself plays fine (maybe even better then on some of my friends machines with windows 10) but the amount of messages (an hour of gaming can yield ~60MB of system log) can get annoying, also I can't help but believe that there is some hit to performance since there are 6 lines of output per frame drawn.
The output is:
fixme:d3d:wined3d_gl_compare_func Unrecognized compare function 0. fixme:d3d:gl_stencil_op Unrecognized stencil op 0. fixme:d3d:gl_stencil_op Unrecognized stencil op 0.
repeated (tens of) thousands of times
IMHO: Ether somebody should investigate the usage of stencil op 0 and fix the code as suggested by the comment of remove the message since the games seems to run fine.
