When an external monitor is connected or disconnected, about 25% of the
time an activity does not resize correctly; a size-changed signal occurs
but the workarea geometry has not changed.
Underlying problem is an update race in get_monitor_workarea, so the fix
is to call get_monitor_geometry for obtaining the width and height.
Can be reproduced easily without an external monitor by switching
display panel resolution repeatedly;
xrandr --output eDP1 --mode 1024x768
xrandr --output eDP1 --mode 1366x768
