All kidding aside, this seems to be a real security issue. Your system
shouldn't be showing unauthorized users what you were doing. It should
properly flush the memory.
I do have a movie clip showing a session where root was viewing the
/etc/shadow file. The shadow is displayed on the screen for about 5
seconds before the KDM login pops up. Ask if you want to actually SEE
this in action just ask and I'll mail it to ya.
Does a power off flush it?
I have power cycled at least one of the machines and let it sit for
several minutes. Also as I stated before sometimes when I get up in the
morning I catch glimpses of stuff I viewed just prior to shutting the
machine down for the night.
Several folks have mentioned it could be related to the ram chips on the
Full-Disclosure - We believe in it.
