>Note, that I had working/stable accelerated intel driver for years prior to  rm-510-kmod.
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

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 within
the Xorg Intel driver or in the drm stack.

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