The hang looks to be a bug in specifying the tiled subsurface on i915g (the offset is probably not sufficiently well aligned). The corruption in the background is just nautilus not redrawing the root window (since 3.8).
** Summary changed: - [i915g] False GPU lockup IPEHR: 0x7d8e0001 + [i915g] GPU hang accessing tiled subsurface -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1232546 Title: [i915g] GPU hang accessing tiled subsurface Status in “xserver-xorg-video-intel” package in Ubuntu: New Bug description: The X-Server did not actually freeze up, only when windows are deactivated ( aka a window that is minimised ) the system doesn't redraw the background of the X-server. See the added example screen shots. ps. I am voluntarily running Gnome-fallback, newer gnome versions all stifle my productivity.
