Bug ID: 36882
           Summary: Modern Era Touhou Games run at abnormally low FPS
           Product: Wine
           Version: 1.7.20
          Hardware: x86
                OS: Mac OS X
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]

In later Touhou Project games (tested 14 and 14.3) in Wine 1.7.20 (and 1.7.21
and most likely before as well, but starting after 1.7.3), the FPS of the games
suddenly drops abnormally to about 20-30 for an inexplicable reason.

The following seemed especially prevalent in the Terminal Window during the
problematic FPS areas (which include the main menu)

fixme:d3dx:D3DXLoadSurfaceFromMemory Unhandled filter 0x30004.
fixme:d3d:resource_check_usage Unhandled usage flags 0x8.

The former is unfamiliar to me, while I have seen the latter before in Touhou
games.

Also, when quitting and exiting the game, the following appeared:

wine(526,0x405d6000) malloc: *** error for object 0x401ca000: pointer being
freed was not allocated
*** set a breakpoint in malloc_error_break to debug

I will be adding bug links and may perform a git bisect if wine-git compiles
for me.
