What do you mean exactly? Is the screen only erased partially, or not at all?
Is there something specific about your setup that you think might be relevant
here?

When I try logging in on the console, and then log out, my screen is erased
completely.

Also, I don't think this bug is really 'grave'. Even if private information
remains on the screen, the user can see that, and take action to avoid it.

Cheers,
