emacs message: timed out waiting for property-notify event

Mark set
Timed out waiting for property-notify event [3 times]

When selecting a large region of code on gnu-emacs like the one shown below I got most of the time the error message above and the command prefix is not recorded (Ctrl-X) so the associated command fails. Cursor moves becomes very slow. Cancelling the selected region revert cursor moves back to normal.

Note: This is observed through a Real VNC session, no idea if this is related with X or not. Any idea or workaround ? Thanks.
