This question I know the answer to. You need to either set your X
server to do backing store, or set IDL to do the backing store fore
you. Most recent versions of XFree86 v.4 have backing store turned
off for some reason. It needs to be turned on with an option in your
"Screen" section of XF86Config:

Option "BackingStore"

This can also be achieved with the RETAIN keyword to WINDOW, but is
more of a pain.

I have no idea about your second question.
