Hi,
the last drm-next-kmod worked fine on my Lenovo T420 with i5-2520M and

ports, I'm seeing regression in form of a very slow xfce4-desktop. The
slowness starts after some short time. Slow means for example that I
can type faster than the terminal prints the chars or when i move
windows they lag extremely behind the mouse's motion.

One entry in Xorg.0.log caught my attention:
[   128.266] (EE) intel(0): Failed to submit rendering commands (Bad
address), disabling acceleration.


Did you build xf86-video-intel with SNA option enabled or have
Option "AccelMethod" "SNA" in xorg.conf? If so see also


# pkg info xf86-video-intel-2.99.917.20180214 | grep -A2 Options
Options:
   SNA: off 
   UXA: on   

# cat /usr/local/etc/X11/xorg.conf.d/driver-intel-mode.conf   
Section "Device"

   Identifier  "Intel Graphics"
   Driver  "intel"
   Option  "AccelMethod"   "sna"
   Option  "TearFree"   "true"
EndSection

Disabling the xfce4-compositor improves the situation significantly, but
not entirely.

Switching back to the systems i915 driver resolves the issue.

Any ideas?



Which version of FreeBSD is this. Are you using the latest kernel 
sources?

Did you build drm-next-kmod from source?


Yes, ports from today built against the revision mentioned above.
