problems with graphics windows in rkward 0.5.6

[Manel]

Binary package hint: compiz

I'm experiencing problems with graphics windows in rkward 0.5.6 (obtained
from https://launchpad.net/~rkward-devel/+archive/rkward-stable). Basically,
the window is closed, directly after opening it. To reproduce
  1. start rkward
  2. wait until the status indicator at the lower right turns green
  3. switch to the "R Console"
  4. type "plot (1, 1)" [Enter].
Expected behavior: A plot window appears.
Actual behavior: No window appears.

Executing step 4 in an R terminal session works without apparent problems.

Note that that the problem does *not* occur with RKWard 0.5.4.

After some diagnostics, the developer of RKWard (Thomas Friedrichsmeier) told
me that it is very likely to be a bug in my window manager (i.e. compiz version 1:0.9.4+bzr20110415-0ubuntu2), and I should open this bug
report incuding the following backgound information:
   - RKWard uses XReparentWindow to "capture" R graphics windows
   - The difference between rkward 0.5.4 and 0.5.6 with respect to graphics
windows is that in rkward 0.5.6, two separate processes are involved. I.e. the
graph window is created from the "rkward.rbackend" process, and it is captured
by the "rkward.fronted" process. Before RKWard 0.5.5, a single process was
involved, only.
   - The windows are reparented from the root window after they have been
mapped
   - This works reliably in many different window managers, including kwin and
metacity
   - It also appears to work ok with compiz 0.8.4-4 on the developer's Debian
sid system.
   - Apparently there have been some recent changes with respect to handling
of XReparentWindow, in response to this bug:
https://bugs.launchpad.net/ubuntu/+source/unity/+bug/743011 . Perhaps this is
related.

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. Compiz, in particular, is in heavy development and this bug may have been fixed in the development version of Ubuntu (12.04) if not on your current version. If you are able, it would be of great help if you could confirm if the bug still exists by testing a livecd (available at ubuntu.com). When you test it and it is still an issue, kindly upload the updated logs by running apport-collect <bug #> and any other logs that are relevant for this particular issue. If you are unable to test the development version, please let us know if you are able to reproduce this issue on Ubuntu 11.10.

Thank you for your help and patience.
