I agree to AW that the root cause of this issue is not the Anti-Aliasing,
because Anti-Aliasing has been introduced after DEV300m30.
OD->AW:
For the check, if a certain Draw graphic object overlaps with the paint region,
the sequences of its 2D primitives is generated. These primitives are used to
determine the geometry of the Draw graphic object in order to compare it with
the paint region.
It seems the determination of their 2D primitives cost some time.
Do you know an optimization for this case?
Can the area taken by the Draw graphic object be determined less "expensive" for
this check?
Does it make sense to check, if the bounding rectangle overlaps with the paint
region, before determining the geometry of a Drawing object?
