I finally managed to get footage of this on hardware lol.

Note: You have almost 100 percent chance of triggering it with a Vita user then with a PSP one for some reason.
But it could still happen with a PSP user rarely even without changing any clock settings.
The PSP emulator that the Vita uses seems to trigger it consistently but if you downclock the CPU it fixes it most of the time.
