             Bug #: 33009
           Summary: Logical error in code isStateDirty
           Product: Wine
           Version: unspecified
          Platform: x86
        OS/Version: Mac OS X
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: directx-d3d
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: roman.marusyk at gmail.com
    Classification: Unclassified


wined3d_private.h have a
static inline BOOL isStateDirty(const struct wined3d_context *context, DWORD
state)
....
(line 1792) return context->isStateDirty[idx] & (1 << shift);

sizeof(BOOL) is not always a 32bits

if someone compile and built only wined3d on macos
BOOL is typedef char BOOL;

and code
return x & (1 << shift) very bad
for example 
return x & (1 << 24) is a return x & (0x01000000) 
if BOOL is typedef char , we have always return FALSE

anyway, better write
    return (context->isStateDirty[idx] & (1 << shift)) != 0;
