I finally have a solution.  It's at the end.

> At NetBSD Startup is your Picasso mounted as a 2M Picasso ?

Yes.  I changed the kernel so that it was a 1M board, but as you
discovered, that doesn't make any difference.

That's normal.  It's just what was there before.

I've never tried GyberGFX.  The Picasso software works well enough for me.

The solutions to the corrupt pointer is to disable the hardware cursor.  It
is done by editing grf_cl.c as follows:

Changes the lines in cl_ioctl from:

            case GRFIOCGSPRITEPOS:
                return (cl_getmousepos(gp, (struct grf_position *) data));
   
            case GRFIOCSSPRITEPOS:
                return (cl_setmousepos(gp, (struct grf_position *) data));

            case GRFIOCSSPRITEINF:
                return (cl_setspriteinfo(gp, (struct grf_spriteinfo *) data));

            case GRFIOCGSPRITEINF:
                return (cl_getspriteinfo(gp, (struct grf_spriteinfo *) data));

            case GRFIOCGSPRITEMAX:
                return (cl_getspritemax(gp, (struct grf_position *) data));

to:

        case GRFIOCGSPRITEPOS:
        case GRFIOCSSPRITEPOS:
        case GRFIOCSSPRITEINF:
        case GRFIOCGSPRITEINF:
        case GRFIOCGSPRITEMAX:
            return (EINVAL);


I now have a perfect cursor in Xcl.


Phil.
