I have noticed a fixme scattered through ./dlls/gdi32/dib.c:

$ grep -n 'FIXME: BI_BITFIELDS not supported yet' ./dlls/gdi32/dib.c
869:                    /* FIXME: BI_BITFIELDS not supported yet */
876:                            /* FIXME: BI_BITFIELDS not supported yet */
937:                            /* FIXME: BI_BITFIELDS not supported yet */
988:                    /* FIXME: BI_BITFIELDS not supported yet */
997:                            /* FIXME: BI_BITFIELDS not supported yet */
1030:                            /* FIXME: BI_BITFIELDS not supported yet */

would it make sense just making sure the output is never compressed (which is
what your suggested patch does)?

an alternative patch:

diff --git a/dlls/gdi32/dib.c b/dlls/gdi32/dib.c
index 440857d..cd48703 100644

I'm not quite clear on this code, so the non-compression patches could still be
problematic. It's hard for me to tell if this is the compression of the bitmap
being copied *to*, or the compression of the bitmap being copied *from*.
