OK, I got my 64-bit computer back and have just tried to reproduce this,
but I can't.  I started mintty, started screen, ran nano, and edited a
large text file, paging up and down through it and adding and deleting
lines.  The display stayed fine.  I tried it a few times with the same
result.

Are you still having this problem?  If so, please follow the bug reporting
