I was wondering whether this could occur when switching to the alternate screen. But it seems that this is not the case, at least not with Xterm's logging feature. So I assume that as long as the user doesn't use a virtual terminal inside the real terminal, things are safe. Users of virtual terminals (GNU Screen, etc.) should be careful, as older data are sent back to the real terminal when switching a window, for instance. However, in case of any issue, the real solution should be to ensure that the printing feature is disabled. -- 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)
