+    You can try running ./configure with the "--curses-hack" option
+    and recompile.  This utilizes a non-portable hack which will only
+    work with certain curses libraries, so it's disabled by default.
+
+    All screen updating is done by your curses library, which means
+    it's not something that Netris can control.  Netris never tells
+    curses to scroll, but curses does so automatically in order to
+    optimize screen updates.  This hack modifies curses's internal
+    variables, making it think that your terminal doesn't know how to
+    region-scroll.
