Display list redraw incomplete

Since compiling R 2.5.0 from source on my Mac (PowerBook) I've noticed
some strange behavior when plotting.  I'm not sure if it's a problem
with my setup/compilation because I feel like a problem as basic as
this one would have been reported already.  I'm running R with X11 and
R was built with gcc 4.0.1.

Basically, I run
X11
  4
Warning message:
Display list redraw incomplete

I don't think I've ever seen that warning before.  In addition to the
warning, two extra x11 devices are launched.  Same thing happens in
R-devel (r41438).  Any thoughts on what might be going on?

Thanks,

Just to follow up with a few more details on this problem (which
persists on my PowerBook Mac but no where else).  I ran a bisection
search on the sources and found that SVN revision 40634 introduces
this problem.  This revision introduced quite a few changes to
'src/main/graphics.c' which I am just beginning to go through.

GIven that I don't see this problem on my Linux box and only on the
Mac, I'm tempted to think this is a compiler issue or perhaps some
weird problem with my setup.  I noticed that I don't have the exact
same gfortran compiler as recommended on
http://r.research.att.com/tools/ but I don't see how that would cause
a problem here.
Otherwise, I am using gcc 4.0.1 which comes with Xcode.

I will keep digging but any pointers would be appreciated.

Thanks,

For the record, I saw the same behaviour a few days back on PPC Linux,
but it was only inside my experimental GUI and not with the CLI. I
assumed it was a problem with my GUI code. The "Display list redraw
incomplete" message was intermittent, but the opening of the extra
windows was fairly consistent (but they popped up and then closed).

I don't remember the exact triggering mechanism, and I don't remember
seeing it recently. I can't reproduce it on my desktop, which is i486
Linux (according to R). I'll try the ppc when I get home.

Hi

Sorry I haven't had time to look at this closely yet.  Some general info
in case it helps in the meantime.

That warning comes from the redrawing of the display list if one of the
graphics system states becomes "invalid".  Because this is a trditional
plot, it suggests that the GE_CheckPlot code in baseCallback() (in
base.c) is returning FALSE.  I doubt that code has changed recently, but
have not checked to be sure.

I have no idea how to explain the launching of two extra x11 devices.

Paul
