This seems to be the same problem as the one I reported a few minutes
ago as «"E36 Not enough room" while sourcing handcrafted session
file». I am now with gvim 9.1.1374 but it has been happening for a
couple of days in earlier versions. Huge version with GTK3 GUI. The
GUI opened with just enough height and width for the menubar, and gave
E36 while sourcing a :new command with filename (and refused to open
that file) until I manually maximized the GUI. Adding a line "set
lines=99 columns=999" before the first :new command in the session
file made the problem disappear. I already had an autocommand "au
GUIEnter * set lines=99 columns=999" (without the quotes), which seems
not to be acted upon, in my vimrc.

Best regards,
Tony.
