Description Havoc Pennington 2002-08-10 04:49:55 UTC 
If I do keyboard resize and move the bottom edge of an xterm way 
down, then way up, then try to go down, some kind of limit on 
downward movement seems to get imposed and the window can't be 
made larger.

This is caused by the so called "smart snap" resizing.
In keybindings.c process_keyboard_resize_grab() we are attempting to
snap to an edge since the resize to the edge is smaller than the
standard resize increment. i.e.:

if (smart_snap || ((edge < (y+height)) &&
                             ABS (edge - (y+height)) < height_inc))
            height = edge - y;


However later in meta_window_move_resize() we end up calling
constrain_size() which ends up making the actual window height less
than the desired edge.

The next time process_keyboard_resize_grab() we try to snap to the
edge again and the cycle repeats.

This code is stuff that should get unhosed a bit when I finish the
constraints.c hacking

Batch adding GNOME2 keyword to Metacity bugs.  Sorry for the spam.
Comment 5 Rob Adams 2003-03-16 00:17:16 UTC 
this appears to be fixed with the constraints.c update.
