If disabling the X11 synch fixes the problem, it probably falls under
bug #1424013 (which is really about broken support for this feature on
older integrated nVidia GPUs in the driver).

If you could follow the instructions in comment 10 of that bug, it could
help with the fix.

Title:
  Unity stopped working after upgrade

Status in compiz package in Ubuntu:
  Incomplete

Bug description:
  After an upgrade last week, Unity stopped working.
  Ligthdm wallpaper (with ubuntu branding on bottom) after login, mouse visible, screen goes black every a few secs, then back to wallpaper and mouse again. 
  Everything worked fine before. Using Ubuntu 14.04.01 (up-to-date), Unity, Nvidia 304-updates drivers.

  I installed gnome2 classic to be able to use my Pc in the meantime.
  Started unity from tty1 with --log option (output attached). Multiple
  compiz (opengl) - Error: FBO is incomplete:
  GL::FRAMEBUFFER_UNSUPPORTED (0x8cdd) seems suspicious.

  What I tried:
  * renamed .compiz, .config, .gconf and .local to force the creation of new default configs. Didn't work.
  * I was able to disable Framebuffer objects in opengl compiz plugin. Got Unity to start, extremely slow and unusable, with the screen going black every few seconds, then normal again, then a black region  moving from bottom to top. Enabled FBO option again.
  * gnome fallback (compiz) didn't work either, only the Metacity version or gnome3 classic, so I guess it's some compiz-nvidia driver issue.
  * Installed new kernel/xorg stack from hardware enablement stack (utopic versions), same issue.
  * Tried nouveau drivers, worked "fine" (as fine as nouveau works on my pc, but at least Unity started normally)
  * Moved to nvidia 304 drivers (no -updates), same issue there. Nvidia 173 is listed as option but won't install.
  * Tried nomodeset kernel option.
  * Downgraded kernel, x server and compiz  to original trusty (no trusty-updates, just trusty), same issue there.
  * Reinstalled ubuntu 14.04.01, same issue after enabling nvidia driver.
  * downloaded ubuntu 14.04.02, same thing.
