Strange, I can reproduce it with uxterm (note that xterm with UTF-8 locales is my usual terminal) and GNOME Terminal. > And if you type cursor down, you get two arrows, one below the line > with no. 2, i.e. where the line should be, but isn't.

With my incoming mailbox, the bug is reproducible after doing Ctrl-L. For instance, Page Up + Page Down yields display issues, e.g. 2931 N 2016-11-30 ... 2932 2016-11-30 ... 9337 N + 2016-11-30 ... 2934 N + 2016-11-30 ... Also, switching screen (which I do quite often, this is one of the main feature of GNU screen) also yields upward shift. One major problem is that due to the shift, the arrow can be on the wrong message (the arrow is at the right place, but the contents had been shifted upwards), and if I type 'd' to delete the message, the D mark appears on the wrong message for the same reason. This means that the message that will be deleted is not the one I expected from the display (I already deleted a wrong mail in the past due to a similar bug, which was this time a character whose wcwdith was 0). Note that it may not be obvious that the contents have shifted upwards, in particular because in my normal config, the help line is not shown. -- 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)
