Afraid I'm also a total wine noob but I'm learning.  Have you given a thought or attempt to these registry tweaks?  They seem to apply to rendering methods, framebuffer is mentioned.



      |  |
      |  +->DirectDrawRenderer
      |  |   [Select what backend to use for DDraw. Valid options are:
      |  |    gdi - Use GDI to draw on the screen (slow but reliable) (default)
      |  |    opengl - Use OpenGL (fast but not all programs work correctly)
      |  |    see http://wiki.winehq.org/DirectDraw for more information]
      |  |
      |  +->RenderTargetLockMode
      |  |   [Selects which mode is used to read and write the framebuffer while it is locked.
      |  |    auto:     same as readdraw at the moment, will do benchmarks and use best method later(default)
      |  |    disabled: effectively disables render target locking
      |  |    readdraw: uses glReadPixels for reading, glDrawPixels for drawing
      |  |    readtex:  reading with glReadPixels, drawing by drawing a textured quad
      |  |    texdraw:  readback using a texture, drawing with glDrawPixels
      |  |    textex:   readback using a texture, drawing with a textured quad
      |  |    see http://wiki.winehq.org/DirectDraw for more information]
      |  |
      |  +->OffscreenRenderingMode
      |  |   [Selects which mode is used to render offscreen images/textures.
      |  |    backbuffer: the rendering is done in the backbuffer (default)
      |  |    pbuffer:    uses PixelBuffers
      |  |    fbo:        uses Framebuffer object]
