R devel - Mar 2012 - windows() device: plot does not refresh with new drawing after opening and closing a new device

Hello,

I see this problem in 2.14.1, a recent dev, and 2.15.0 alpha, but not
in an older build.

Start the R windows console and run this code:

plot(1:10);windows();dev.off();points(10:1)

The second set of points does not show up until the window is
minimized and restored.

If the device is replaced with a file-based one (pdf, png) there's no
problem.

I see this behaviour on these versions:

  R version 2.15.0 alpha (2012-03-13 r58726)
  Platform: x86_64-pc-mingw32/x64 (64-bit)

  R Under development (unstable) (2012-02-28 r58513)
  Platform: x86_64-pc-mingw32/x64 (64-bit)

  R version 2.14.1 (2011-12-22)
  Platform: x86_64-pc-mingw32/x64 (64-bit)

I have an old beta install of 2.13.2 where the problem does not occur:

  R version 2.13.2 beta (2011-09-22 r57035)
  Platform: x86_64-pc-mingw32/x64 (64-bit)

Cheers, Mike.

Definitely looks like a bug.  I'll see if I can track it down.

The problem is caused by events happening asynchronously:  the first 
device is made active before the second one is closed, and closing the 
second one cancels the pending updates.  We should be able to get it 
fixed before 2.15.0; in the meantime, a workaround is to call 
dev.flush(), e.g.

plot(1:10);windows();dev.off();points(10:1);dev.flush()

should be fine.
