wmctrl -l does not list all open windows

[Jani Uusitalo]

I have two Chromium windows open, 0x31fd46b and 0x3072dc8 (this one):

But wmctrl only knows about the one:
jani@saegusa:~$ wmctrl -l

0x04200009 0 saegusa Kuvakaappaus
0x04600081 0 saegusa Synaptic-pakettienhallinta

This may be related to the fact that the other window has fallen out of view: it's not visible on any workspace, but it's still there as the audio's still playing. It got out of sight due to another bug (probably in Compiz) which I have yet to report.

This looks a bit like RH 426383 [1], but isn't as grave as that one (all windows apart from the one) are shown here.

Status changed to 'Confirmed' because the bug affects multiple users.
