See screenshot attached below (in 1st comment. Right side and bottom of screen
remain black, scaling failing)
STR:
1. enable scaling, set it to 125%, apply the setting.
2. disable the scaling toggle and click apply, without changing the "scale"
value itself
Issue does not appear when first applying "100%" scale before applying
the toggle-off change.
