Thanks Gilboa for the quick answer. As I understand it, the behavior
I reported is the SAME with any desktop environment tried so far
(cinnamon mate, non-gnome stuff...)

Things are more complicated by one important thing I forgot to 
say,sorry: I have no
**continuous** direct access to that box: it's in somebody else's house,
*without* broadband. I do have ssh access to it, and root password,
but anything that involves downloading lots of packages and/or
plugging a live CD or installing F22 in there may have to wait weeks. If 
at all possible,
any temporary improvement that can be achieved through a slow terminal, 
or giving
a few simple instructions (click there, then there) over the phone
would be a livesaver for the "end user".

So, how can I test your hypothesis quickly? Is it possible to test it
disabling acceleration (how?) and/or changing configuration in other 
ways
(passing option to the kernel, changing configuration files (which 
ones?)
without installing all possible desktop/windows manager and trying
to work with each...
