Screen tearing after xorg-server update to 1.20.8,1 (Intel HD)

Just updated my xorg-server to 1.20.8,1 and noticed horrible screen tearing in all applications which wasn't present before with 1.18. I wonder if anyone has any ideas how to fix it. I'm using:

- FreeBSD 12.1-RELEASE r354233 GENERIC amd64
- drm-kmod compiled from ports
- Intel HD Graphics 520 on ThinkPad X1 Yoga (1st Gen).

Thanks.
 
Try the 'intel' driver with the "TearFree" option.

To do that, create a new file driver.conf in /usr/local/etc/X11/xorg.conf.d/ with the following contents:
Code: 
Section "Device"
  Identifier "Intel Graphics"
  Driver "intel"
  Option "TearFree" "true"
EndSection

I think we're supposed to use drm-kmod and not the intel driver.

drm-kmod works with both the modesetting and the intel driver. The former is being used by default.
You're right, one should use modesetting rather than intel, but for me intel works much better.

I think it's worth a try.
 
Many thanks for the wisdom. This has fixed the issue. Amazingly, I've had to use modesetting because I had huge tearing and CPU load issues with xorg 1.18. With 1.20 it's the other way round.
