Just of note (not sure if this helps), but I also found that the xserver-xorg-video-intel driver from the oibaf/graphics-drivers PPA also fixed an issue I was having with waking the monitor up from standby or sleep on my machine. Before it was freezing and I'd have to either reboot or run 'sudo service lightdm restart' to fix the problem. Now, there's no issue.
So, it seems that the shadow bug triggered by GTK 3.14 and the wake from sleep issue were both corrected by the driver in that PPA, and not having to update all of xorg. Sadly, I cannot point to a specific commit at this time, but I might be up for bisecting the driver. -- 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/1378188 Title: [GNOME3 Staging PPA] strange shadow rendered where client-side decorations are used Status in xserver-xorg-video-intel package in Ubuntu: New Bug description: When using apps where client-side decorations are being used, a strange shadow render appears below the window.
