Summary: Painkiller second boss level unplayably slow -
                    drawStridedSlow issue on water rendering? with fbo.
           Product: Wine
           Version: 1.1.16
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: -unknown

        ReportedBy: [e-mail]

The second boss level in Painkiller, which features a lot of water effects, is
unplayably slow in Wine 1.1.16 (something around 1 or 2 frames per second). The
rest of the game, which doesn't have any water effects, has perfectly
acceptable frame-rates, at least 30 to 40 fps.

During this level (and not during any other level so far), Wine spams the
console with:

fixme:d3d_draw:drawStridedSlow >>>>>>>>>>>>>>>>>
GL_INVALID_FRAMEBUFFER_OPERATION_EXT (0x506) from glEnd and previous calls @
drawprim.c / 516
fixme:d3d:context_check_fbo_status FBO status
GL_FRAMEBUFFER_INCOMPLETE_DRAW_BUFFER_EXT (0x8cdb)
fixme:d3d:context_check_fbo_status      Color attachment 0: (0x6590a80)
WINED3DFMT_X8R8G8B8 512x512
fixme:d3d:context_check_fbo_status      Depth attachment: (0x5f9c1e8)
WINED3DFMT_D24S8 512x512

repeating endlessly (so much so that I can't tell which line is the start of
the pattern and which is the end).

Obviously, I'm using the fbo for Offscreen Rendering.
Will retest with backbuffer enabled.
