A friend of mine had a problem with incorrect display of the Russian fonts with Googleearth installed to the default location at /opt/googleearth.
To fix this, do the below:
sudo yum -y install kcm-gtk cd /opt/googleearth sudo mkdir old sudo mv libQt* plugins/imageformats/* old/
Works well after restart of Googleearth. Tested on HP Compaq CQ71 laptop.
