  We revisit the hard QCD contributions to the pion gravitational form factors
(GFFs), in terms of the twist-2,3 pion distribution amplitudes (DA), including
novel semi-hard contributions from the instantons. The pion DAs are evaluated
in the QCD instanton vacuum, and then properly evolved to higher resolution.
The results are compared to our recent results from the QCD instanton vacuum,
as well as Bethe-Salpeter calculations and recent lattice data. The
interpolated hard and soft contributions to the pion D-form-factor, are used to
derive the (gravitational) pressure and shear within the pion, with a clear
delineation of their range.
