lynx-dev problems with drawing in lynx-2.8.2dev.12

 I've compiled lynx with color style support.
 I have a problem with it: after it completely draws the screen (it's visible
 for short period of time, like 0.2 sec) , the screen
 goes black (ie all characters that were drawn in normal colors became
 invisible = black) with only currently selected link visible (in the proper
 color), status text at the bottom and status text at the  right upper corner.
 I've specified black background for all attributes in my lss file. It looks
 like it issues some ioctl to the terminal after drawing, and then draws the 
 active link in the corresponding color.
   I'm using i386-RedHat5.2 (linux kernel 2.0.36) I've also compiled the lynx 
 on the i386-RedHat5.0 - the same thing happens. Since ncurses is the same as 
 curses under linux, and lss support is disabled for slang, it may be something 
 with ncurses (but unlikely). I tried to compile lynx with ncurses-1.9.9e and 
 ncurses-4.2 -no difference. This behavior is observed under with x-term,rxvt 
 and native linux-console.

   I had to switch to lynx-2.8 (I use lynx-2.8, March 10, 1998 ) due to it.
 
 I tried to compile with and without partial display logic - no difference.
 This problem happens only for html files, that are longer than a screen. 
 This problem happens only to htmls that are non-cached (ie were not visited).
 When the problem happens any action that forces lynx to redraw the screen 
 draws screen as it should be except for ^R (ie ^L redraws the screen as it
 should be, PAGEUP|PAGEDOWN also redraws it). Pressing DOWNARROW or UPARROW
 will cause the corresponding link to be drawn only - nothing is drawn except
 it (previously selected will be displayed in the color, in which passive link 
 should be). Escaping back (via pressing LEFT) and then forth (RIGHT) will also
 force the lynx to draw the page properly.
 
  This problem doesn't happen for ALL htmls that are bigger than a screen, 
 there are huge files (~300Kb each) for which this problem doesn't happen.
 I observe this problem on TOCs of
    "Linux Installation and Getting Started guide"
    "Linux System Administrators' Guide"
    "Linux Programmer's Guide"
    
 Has anybody reported this problem?    

 Here is my configuration: GCC 2.8.1, linux kernel 2.0.36, ncurses 4.2
./configure --enable-forms-options --enable-menu-options \
--enable-config-info --enable-alt-bindings --enable-kbd-layout \
--enable-color-style --enable-gzip-help --with-zlib --enable-dired \
--enable-dired-archive -enable-dired-override --enable-dired-permit \
--enable-dired-tar --enable-dired-uudecode --enable-dired-zip \
--enable-dired-gzip --enable-parent-dir-refs --enable-partial
