when running vim under Solaris, terminal doesn't refresh properly

[Langella Raphael]

Hi,
I'm running GNU Screen 4.00.02 under Linux RHEL 4u5. vim works fine under 
Linux, but if I ssh to a Solaris machine from within screen, then I've got some 
problem with vim. When I edit a file, I've got some garbage after the end of 
line. Characters from the file I'm editing are properly displayed, but when the 
line is short and doesn't fill up my screen, the end is not cleared, I see some 
leftovers from my shell session or from previous vim edit.
    I've tried to change the term to xterm, sun-color or the default 
screen-bce, but it's the same. I've tried with vim 6.3 and the latest 7.2, same 
problem. I'm not sure if the problem comes from screen or vim or Solaris. I've 
also tried to google for it, but I find this problem very hard to describe with 
keywords. Some directions would be greatly appreciated.
Thanks for your attention.
