I'm not really seeing a problem on Linux, but the console enters a wait loop
to respond to commands and maybe the way that loop was defined was not
allowing sufficient cycles for updating the GUI. I've made a change that
might help in my working copy but unfortunately I can't push it right now as
sourceforge git access isn't working.

After pulling this in, my gretl_x11 uses 100% of one CPU when the console
is open.
