The size of the brush is set by the Size setting in the options of the
painting tool you use. Thus a brush no longer has only one intrinsic
size.

It uses it in a random sequence! If you want to use the gradient in a
non-random way, define a new paint dynamics, and check a box in the
Color line of its Mapping matrix, for example Pressure or Direction.

Don't understand what you're telling. What painting tool and what
exact brush are you using?

You have to define a new paint dynamics. Use the second or third
button in the bottom of the Paint Dynamics dockable dialog.

Because you are asking for randomness.

Set the opacity of your brush to 50%, and try it with or without
"Incremental" to see what it means.

For "Smooth stroke" try the Paintbrush tool with the Block 01 brush,
set the options of Smoot stroke to their maximum, and try with or
without checking the option.

Your distribution or installation is not important, but these features are new.
