Default: lower=_500000_ (0.5ms), upper=_8333333_ (8.3ms - half a
frame interval).
*damage-whole-window*
Boolean. When enabled, foot will 'damage' the entire window each
time a frame has been rendered. This forces the compositor to
redraw the entire window. If disabled, foot will only 'damage'
updated rows.
There is normally *no* reason to enable this. However, it has been
seen to workaround an issue with _fractional scaling_ in _Gnome_.
Note that enabling this option is likely to increase CPU and/or
GPU usage (by the compositor, not by foot), and may have a
negative impact on battery life.
Default: _false_.
*max-shm-pool-size-mb*
This option controls the amount of *virtual* memory used by the
pixmap memory to which the terminal screen content is rendered.
