Dialog Grid % Adjustments (in the Dialog Sizing dialog) of less than about five percent were often not having any effect, due to rounding. The scaling logic now delays rounding until later in the calculation, permitting adjustments of as small as one percent.
Note that the dialog font scale factor is still applied to the grid unit and rounded down to an integer pixel size, so font scale changes of less than about 5% may not have an effect. (Or it may affect the height but not the width.) For example, if the grid cell is 13 wide by 27 high, and you increase the dialog font scale factor by 5%, the new grid cell will be 13 wide by 28 high. (The 5% is not enough to increase the width by an entire pixel.)
