This issue was happening a lot to owners with ATI drivers + compiz fusion + Google Earth.
I was using Ubuntu 8.04 before on the same machine and GoogleEarth was working perfectly. That means that is a way around solve it.
The only temporary fix that I have know is disabling Compiz on the Fusion Icon. Everytime that I want to use Google Earth.
I know that there are other people with the same issue or similar with GoogleEarth.
If someone have another work around that is not using an older Lib file from an older ATI driver let me know please.
