Well, for lots of bugs, the behavior doesn't make sense. That's why they are bugs. Thus it may be a good idea not to leave private data behind, in case there would be such a bug. Similarly, there is (was?) this old Xorg/nouveau bug that may reveal parts of the user's desktop after reboot (which is problematic on a shared computer). Displaying old video memory (not erased at logout or at shutdown) doesn't make sense, but this happened. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
