Comment 98 for bug 940603

Ok all.

I'd like to see if this is a window or something else. Since we can't xwininfo it, I wrote a small plugin which allows you to navigate to a window and dump its contents.

lp:~smspillaz/+junk/sdump

So you'll need to install compiz-dev and then

bzr branch lp:~smspillaz/+junk/sdump
cd sdump
mkdir build
cd build
cmake ..
make && make install

And then go into ccsm and enable the sdump plugin (protip, you can prevent the crash on enabling plugins by going into advanced settings, disabling auto-sorting and selecting sdump from the left list and moving it to the right list).

Once you've done that and manage to reproduce the white window, use super-n and super-p to move the blue rectangle to the white window (if possible) and then press super-d to output its contents to a terminal or.xsession-errors. Post the output or the .xsession-errors here
