window dissapear after system upgrade [solved]

hello. I had a problem with gnome on Calculate linux 11.9. after I did a system upgrade gnome destroyed. window no close, open and minimize but if I use root user everything is fine. what should I do?. thank you
sorry if my english is not good

Looks like compiz doesn’t work. What shows commands:

grep compiz ~/.xsession-errors

grep compiz /var/log/Xorg.0.log

grep EE /var/log/Xorg.0.log

thank you for your answer. but I had already re-install. but my question now is how do I refuse to upgrade the kernel? sorry I have not experienced with gentoo system. Calculate is a good distro for me who does not have enough bandwidth

The file /etc/portage/profile/package.provided, you can list packages. Portage will assume that these packages are installed. Unfortunately the file format includes reference versions.

thank you very much for the reply, everything is running smoothly after system upgrade
