[FIXME] Ugly Issue in composited Environment

[Christopher Roy Bratusek]

Hi Crew,

in non-composited environment animations happens as follows:

- click iconify button
- window disappears
- animation is beeing run

but in composited environment it's a bit different
... more precisly -ugly-:

- click iconify button
- window _does not_ disappear
- animation is beeing run
- _now_ the window disappears

Any hint?

Chris
