Did I found a bug?

[Vlad Volodin <vest 84 gmail com>]

Hello, dear developers.

Today, I've downloaded gnome-games from svn trunk. I've compile them
with --enable-clutter support and --enable-games=all (here is my
configure script output http://paste.org.ru/?9gbmkr ). Then, usual
make and make install. So, I decided to check gnometris and aisleriot.
I've found several issues. maybe you can help me with them. (I'm not
sure, should I use Bug system in this case)

when I started gnometris and opened it's preferences, I saw this. The
clutter's view will be refreshed good after changing tabs.
Is it clutter error, or mine? I'm programming with clutter-0.9, got
from GIT, but Gnome Games are required clutter API 0.8 (I have
libclutter 0.8.8)
$ pkg-config --list-all | grep clutter

If I use two cards in aisleriot (thirteen or pyramid), their empty
spaced are not moved to back position. When I use aisleriot without
clutter support, everything goes fine
(http://img10.imageshack.us/img10/2742/32831421.png), but I'm not
sure, should aisleriot draw focus around it's empty spaces (if I click
on them).

Thank you all in advance,
Vlad Volodin

p.s. I'm still using Ubuntu 8.10 with the newest GTK+ in their branch,
but I use the newest clutter.
