Yes. Turn off the x11 resource "fastrotate".

echo "gnuplot*fastrotate:  off" | xrdb -merge



This is a known, and long-since discussed, problem.
To rotate text correctly in the presence of extra colors is *very* slow,
to the point that x performance is seriously degraded.
Since most plots do not need this feature, the default is to use the
older, faster, rendering algorithm.
