This is going to be a somewhat annoying test, but for those that have this issue, specifically with the 320M which is the GPU affected by the corruption (the 330M may also be affected but virtually no reports have come in from owners with that GPU), could you boot up to safe mode and run your apps for a moderate period of time? This will disable GeForce.kext and essentially give you a very stutterific experience, but with the driver disabled, it should help determine if this is a major driver issue or a power management problem such as the Kepler based 680 Mac Edition is seeing.
Trust me, this definitely has not gone unnoticed, especially in games. Every last complaint of corruption from players comes from the Macs with the nVidia 320M GPU and Mavericks.
I'd like to determine just how badly done these nVidia drivers really are, especially given that despite the Apple version numbers, the nVidia version numbers put the drivers at being older than the 10.8.5 nVidia drivers, to say nothing of the nVidia Web drivers from 10.8.5.
Something pretty significant must have happened between the DP versions and the release version of the nVidia drivers (and AMD too as those lost significant performance). The DP drivers brought OpenGL performance almost exactly on par with Windows' DX11 performance in two of their versions, and then the Mavericks release just totally went in the opposite direction.
Please try safe boot to see if the corruption persists. Any test data that we can collect will be greatly appreciated. You don't have to spend all day on testing safe boot mode - just long enough to where you would normally start experiencing the corruption on a regular boot should suffice.
