I haven't heard about this workaround but it makes lot of sense. Many of
slugish reports seems to be related to X<->drivers traffic. To check whether
this is your case then try to scroll and look via e.g. top on the usage of
your CPU - if X is taking 80-90% and LyX 10-20% then you have probably this
kind of problem.
