gnome-terminal max_size and resize looses 1 row and 1 colomn

[Bernhard Riegler]

I installed "xterm" to get utility "resize" and have a comparison between 2 terminal programs.
xterm works. between the "resize" commands is double click on top bar (max.size, restore)
bernie@prod:~$ resize
COLUMNS=80;
LINES=24;
export COLUMNS LINES;
bernie@prod:~$ resize
COLUMNS=80;
LINES=24;
export COLUMNS LINES;
bernie@prod:~$ resize
COLUMNS=80;
LINES=24;
export COLUMNS LINES;
---------------------------- stable columns,lines with xterm
gnome-terminal has a bug. again (max.size, restore) with double-click on top bar.
bernie@prod:~$ resize
COLUMNS=80;
LINES=24;
export COLUMNS LINES;
bernie@prod:~$ resize
COLUMNS=79;
LINES=23;
export COLUMNS LINES;
bernie@prod:~$ resize
COLUMNS=78;
LINES=22;
export COLUMNS LINES;
----------------with every cycle the gnome-terminal looses 1 row and 1 column

I assume an "integer division" cut down
my HW monitor has a screen resolution of 1920 x 1200 pixel.
