FIXME's and missing buttons

[Dan]

Hey there.  I am running a program call SciFinder Scholar (it searches
research journal pub databases) under codeweavers wine preview 4.

Program runs pretty well  EXCEPT
all of the toolbar buttons are blank.
and there are a fair number of the following errors

fixme:bitmap:X11DRV_DIB_GetImageBits_1 from 1 bit bitmap with mask R,G,B
ff0000,ff00,ff to 1 bit DIB
fixme:bitblt:MaskBlt (2572,214,196,210,24,2552,0,0,2684,0,0,-1429471232):
stub
fixme:bitblt:MaskBlt (2572,214,196,210,24,2552,0,0,2688,0,0,-1429471232):
stub

I would like to contribute..and actually FIX the fixme's instead of just
sitting here whining about my wine not working.  Can someone give me a few
pointers (such as if the blank buttons ARE related to the errors) so that I
can try and get the button graphics.
