Public bug reported:
Binary package hint: libgl1-mesa-dri
Setting the saturation for a composited window to less than 100%
abruptly turns it into a solid white/grey rectangle. Its content stays
invisible until the saturation is returned to 100%. This happens in
compiz with unresponsive windows via the "Fading Windows" plug-in as
well as when manually setting saturation with the "Opacity Brightness
Saturation" plug-in. Opacity and brightness are unaffected and work as
expected.
Steps to reproduce:
$ gnome-calculator&
$ killall -s STOP gnome-calculator
-> wait and watch gnome-calculator become solid grey (see screen shot)
or:
$ gnome-calculator&
$ ccsm
Accessibility->Opacity Brightness Saturation->Saturation
press "new ", Windows: class=Gnome-calculator, Window values: 99
-> gnome-calculator turns solid white
