Thanks for report, yes, I can also reproduce with xterm,

Without looking at code, it probably needs to call one of resize functions after "attaching" to new session.

I should mention that I'm using gnome-terminal, and that resizing the gnome-terminal window causes the screen window to get the correct number of lines set. It's possible other terminal emulators mask the issue.

If you open a window using the screen command in your screenrc before you set your hardstatus to use the (always)lastline option, the window won't set its number of lines correctly to account for the hardstatus line. Consider this screenrc:

screen 1
hardstatus alwayslastline "hi "

If you open screen on a 24 line terminal, the window opened as a result of the "screen 1" command will have its number of lines set to 24 instead of 23 (stty size reports 24 rows). That is, it won't reserve a line for the hardstatus line.

Windows opened outside of the configuration file, or windows opened after setting the hardstatus to use lastline, have the correct number of lines (stty size reports 23 rows). Furthermore, if you open multiple windows in the screenrc like so...

screen 1
screen 2
screen 3
hardstatus alwayslastline "hi "

...only "screen 3" is misconfigured.

I've observed this issue in version 4.03.01 and builds from git source as of Feb 18 2018.
