That is not so for the default type="cairo". The problem is likely to be that the bitblt is across the network, whereas repaint is a bitblt from a local copy. There are some comments on the X11() help page -- you may want to try type = "nbcairo". Some changes are planned for R 2.8.0 which will improve performance, but for now things are tuned for the most common case of a local X11 display (although type = "nbcairo" works quite well over my home wireless network). > > R version 2.8.0 Under development (unstable) (2008-04-05 r45102) > > Thank you again for tracking down the original issue. > > Martin > > Prof Brian Ripley <[EMAIL PROTECTED]> writes: > >> I think I have found this -- if so, it was an X11 timing issue and we >> needed to re-read the X11 window size at a later time.
