Since the November 2012 update to Moutain Lion, I keep getting these weird graphical issues.
The list of woes:
OpenCL crashes during application startup
Sometimes after the laptop wakes up from a long sleep, when trying to launch any applications, they all crash with the following kind of stacktrace exhibiting a problem in CoreImage/OpenCL:

Graphical corruption
I experience the same graphic artefacts (white noise) corruption overlayed on different UI elements like opened windows, the Finder icons in the Cmd+Tab list, background image,... like so: Screenshot
For corrupted windows, any action that issues a repainting cures the issue but the others (Finder icon, background image) stay (probably because they never repaint) until the computer is rebooted.
Broken icons
In what is a persisting problem afterwards (even after rebooting), any template icons (or otherwise shader-processed-behind-the-scenes icons) disappear from places like status bar/toolbar/side-panels:
For this last one, the usual tricks of creating a new user or reinstalling a prior version work in the beginning but the issue resurfaces later.
Since I have FileVault turned on, I also can't seem to be able to boot into safe mode to flush the icon caches manually (same 25-30% stuck loading bar problem than described elsewhere).
Cleaning whatever other Caches folder I can find doesn't help either.
Now, the interesting thing is that problem 1 and problem 3 are both circumvented with a simple action: running the application manually from a terminal (as in, not via open(1) i.e. not with launchd as the parent process).
In that case the icons renders perfectly and there is no weird OpenCL crash for the lifespan of that instance although it doesn't fix the problem for normally launched applications afterwards.
As I scouted the internet I couldn't find people with precisely the same set of issues so it could simply be that my machine is faulty but I'm posting here beforehand to see if anyone else has more ideas on how to diagnose the problem (and to provide a Google entry-point for it).
