[compiz] Invisible window problem

[Mike Dransfield]

There is a bug which I am seeing and a few people are reporting
on the forum.

The problem is a hidden window which is always rendered on
top.  It is always short and wide and appears near the
bottom-center of the screen.

Here is the output from xwininfo on that window, xprop produces
nothing.

xwininfo: Window id: 0x3400787 (has no name)

  Absolute upper-left X:  294
  Absolute upper-left Y:  413
  Relative upper-left X:  294
  Relative upper-left Y:  413

  Height: 264
  Depth: 0
  Visual Class: TrueColor
  Border width: 0
  Class: InputOnly
  Colormap: 0x0 (not installed)

  Corners:  +294+413  -294+413  -294-373  +294-373
  -geometry 1092x264+294+413

Is there any other debugging information I could get on this?

The bug was introduced just before the release of 0.3.6 and is
present in that release and current git.

Does this sound familiar, or should I report it as a bug, it is
very annoying because the window blocks clicks so you have
to move windows up to interact with them.
