Problem Description:
      When the colormap size is 65 or more except (256), the
      background of the window becomes white instead of black and
      some colors of graphics primitives are not correct on 4.1.1.
      When the colormap size is 32, 64, 256, the background of the
      window appears correct (i.e. black).  But when the colormap
      size is 30, 65, 128, 245, the background becomes white.  I
      tested this on a SS2 GX and a SS2/GS running 4.1.1 Beta.

      It will only happen under the following circumstances:
      (1) the window colormap segment is placed starting at entry 0
              but is not a cmshog
      (2) the background color of the window is the same as the
              foreground color of the entire window system


INSTALL:

This fix will require reconfiguring your kernel.  Information on kernel
configuration procedures can be found in Chapter 9 of the "System &
Network Administration" manual.

The following file must be replaced:
      /usr/kvm/sys/sunX/OBJ/windt.o
where "sunX" is one of sun3, sun3x, sun4 sun4c

2. Save the existing object file (in case of accident).
      
    tutorial# mv /usr/kvm/sys/sunX/OBJ/windt.o /usr/kvm/sys/sunX/OBJ/windt.o.orig

3. Copy the replacement file into the sys area.

      tutorial# cp sunX/windt.o /usr/kvm/sys/sunX/OBJ
      tutorial# chmod  444 /usr/kvm/sys/sunX/OBJ/windt.o

4. Reconfigure and install the new kernel.
