Hi, I should have been paying attention to this bug by now, since I have
Intel(R) HD Graphics 530 (Skylake GT2).  With what has been available in po=
rts,
everything since DRM 4.9 kmod (drm-fbsd11.2-kmod-4.9g20181023) has been
unusable: With "intel" driver and SNA+TearFree, after a few minutes of Xorg
running, or even after launching Firefox, performance becomes terrible, whe=
re
it feels as though in each 1/60th of a second, there is only a one in three
chance of a frame getting pushed to the display).  "modesetting" has never
worked for me with any drm-kmod without tearing, so I do not use it.  Here I
thought I was the only user of Intel HD530 and the only one stuck on DRM 4.=

Jan, has this been your experience with "intel" driver?  Is this one thing =
that
the update fixes?

As long as DRM 4.9 continues to build and run on FreeBSD 12.x I haven't been
able to justify putting enormous time into debugging the newer graphics sta=
ck,
but it sounds like this update may be the fix; I can't tell.  (If you'd rat=
her
I just try it than ask questions then that is an option for me but it may d=
elay
my willingness to test it indefinitely).
