+Subject: [PATCH] xclearwin clears the window
+
+When an OCS sequence was used to change the bg color, the borders where
+dirty. This simple patch just clears the window before the redraw of the
+terminal when the bg color has been changed. This is apparently enough
+and seams to be very smooth. There was a TODO comment for it on the st.c
+file, which I removed.
