I tested this on my Mac Studio M4 Max running Sequoia 15.7.9. The only browser I use other than Safari (which requires Tahoe for WebGPU) is Opera, so I tested it there.
When I click the death ray, it freezes Opera completely, and pins my 40 core GPU at 100% indefinitely.
However, contrary to what should happen, macOS continues merrily along. It lags a bit and some UI elements don't appear instantly, but I can summon the force quit menu and simply kill Opera, at which point the OS returns to normal.
However, there *is* _something_ confused, as my GPU is sitting at 6W and full boost, yet with no active processes. Seems to suggest that something is orphaned yet still running. I am now going to log out and back in to see if I can fix it without rebooting.
EDIT: fixed the 100% use, but not the power draw, by putting it to sleep and waking it back up. Interesting!
