Comment 0 for bug 975689

When I run google-earth 6.2.1.6014-r0 using the Sandy Bridge GPU, X freezes while zooming in on a location. For instance this happens when I type 'Caversham WA' into the Google Earth search: X freezes about half-way through the animation.

This happens in Unity, Unity2d, or gnome-shell in Ubuntu 12.04.

X completely freezes so that I can't even switch to a tty console. However, I can still ssh into the machine from a remote location. Restarting lightdm has no effect but I can reboot the PC.

If I run google-earth through the nvidia card on this PC (using bumblebee/optirun) there is no problem. google-earth also runs fine in a VM on this machine using the VirtualBox OSE graphics drivers, and it also runs fine on another PC with only an nvidia card.

The Xorg.0.log file reports "EQ overflowing" and gives a number of backtraces (the Xorg.0.log is attached in case apport didn't find it).
