You seems to consider modesetting as no hardware acceleration.
Most likely, modesetting would use Glamor as hardware acceleration.
A kind of hardware acceleration that use the card 3D to achieve 2D
acceleration.

Old 2D acceleration, is I believed, a bit forgotten by developers... because
they prefer Glamor.

Also, and I am less sure... I think Glamor also used the drm stack... so
testing with Intel would allows like help to determine if the problem is wi=
thin
the Xorg Intel driver or in the drm stack.

But yeah... frankly I think most people should just use modesetting with Gl=
amor
acceleration and avoid the Xorg intel driver.
