This bug is easily reproducible using nvidia-binary drivers (even the latest experimental) on Saucy/Precise; however you need to set your nvidia driver into a low performance state. You can use an xorg.conf with the following:
Section "Device"
    Identifier "Device0"
    Driver "nvidia"
    VendorName "NVIDIA Corporation"
    BoardName "Quadro 600"
    Option "RegistryDwords" "PowerMizerEnable=0x1; PowerMizerDefaultAC=0x3"
EndSection

Then I've been able to reproduce simply by opening xterm, and typing
dmesg a few times until I see missing text.

To workaround this issue I can use the following setting in CCSM:
CCSM -> Workarounds -> Force full screen redraws (buffer swap) on repaint [force_swap_bufferss]

I've also tested the latest PPA from ppa:smspillaz/compiz-experimental
(compiz 1:0.9.10.2-1-experimental1+bzr3747-201306271732~saucy1) and
found that the following experiment still produces corruption, but
within a second or two it gets rendered properly.
