As this seems to have gotten bumped, I went and tested with yesterday's
drm-tip.

Here we can see cam footage of the moment the GPU dies:

The corruption of the desktop never exceeds the top ~5%, but parts of that top
portion will occasionally get overwritten. Notice how all of the corrupt fonts
magically clean themselves once they get re-rendered in software.
