It's a known issue, but I've yet to find a comprehensive explanation for what's
going on.

What X crash? The bugs show a GPU hang. X itself should remain stable
through such a catastrophe and revert to software rendering (if the GPU
becomes wedged). If you have an instance where X itself fails, please do
let me know.

Appears to be caused by the Hi-Z code. No known solution at this
point, aside from disabling Hi-Z. Here's a script that I use to launch
google-earth with Hi-Z disabled (and enough core fonts to make the
broken Qt version included work):
#!/bin/sh
export INTEL_HIZ=0
MISCFONTS=/usr/share/fonts/X11/misc
if xset q | grep -q "$MISCFONTS"; then
echo 'fonts already present'
else
xset fp+ /usr/share/fonts/X11/misc
fi
/usr/bin/google-earth "$@"
