I just updated to Christopher Townsend's repo. This update seems to have fixed the problem for me. It's only been five minutes, but I've tested the situations that were most frequently exhibiting this problem (editing files in Vi within Guake while using pageup/pagedown to scroll, and scrolling through my song list in Quod Libet and then making a different window active right after that.)
I'm running GTX 560 Ti with NVIDIA 337.19 and Kernel 3.13.0-29-lowlatency x86_64 and fully-updated Ubuntu 14.04. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/1288747 Title: [334] Parts of the UI randomly flicker when moving the mouse Status in Compiz: Triaged Status in “compiz” package in Ubuntu: Triaged Bug description: Nvidia 334.21 makes the UI jearky, googled and found this on Nvidia forums: "This looks like a problem caused by the system compositor not properly waiting for X rendering to finish before performing OpenGL rendering in response. The GL_EXT_x11_sync_object extension was designed to solve this problem, but it looks like cogl (the back-end library used by GNOME's compositor) doesn't use it yet.
