I915 Graphics and tearing

Hi, since I installed Manjaro for the first time on February 2019, I never faced the Tearing issue, but since some update ago (I am on the stable branch), the video tearing has begun to appears. I can’t exactly recall which update was the culprit, but by doing a research, seems this one, since another user reported the same in this reply: [Stable Update] 2019-07-03 - Kernels, Systemd, Pamac 8.0, KDE, XFCE, Browser, QT which seems due the Mesa update.

I have been able to get rid of tearing by making the file /etc/X11/xorg.conf.d/20-intel.conf with the following entry Option "TearFree" "true", but this option is discouraged: https://wiki.archlinux.org/index.php/intel_graphics#Tearing
and anyway is just a workaround (needed due a regression) , since previuosly I never faced tearing, also thanks to the compositors (the one shipped by XFCE and/or also by using Compton instead – my current Compositor).
What I noticed since I am using the option TearFree, is that the scrolling in the apps (expecially in the browsers) is not fluid as before.
Is the current development of Mesa aware of this issue (ever if is Mesa the culprit)? What about if I attempt to downgrade Mesa? Could I risk to encounter other issues? I am aware of the fact that the downgrade of certain components is discouraged as well.

My specs:
Graphics: Device-1: Intel 3rd Gen Core processor Graphics vendor: Hewlett-Packard driver: i915 v: kernel bus ID: 00:02.0 Display: x11 server: X.Org 1.20.5 driver: intel resolution: 1366x768~60Hz

Current version of Mesa package: mesa 19.1.3-1

Manjaro using OWN setup Xorg in /etc/X11/mhwd.d/intel.conf
and delete Option "TearFree" "true" if you will change to uxa.
Delete second file /etc/X11/xorg.conf.d/20-intel.conf if you created.
sna is buggy for older gen. Switch to UXA
replace sna to uxa

Option      "AccelMethod" "uxa"

Save changes. Reboot.

Hi, I followed your insctructions (disable TearFree and replace SNA with UXA in such mentioned config file and then reboot) but the video tearing is back, is not solved: However I never experienced issues with SNA AccelMethod as reported here: https://wiki.archlinux.org/index.php/Intel_graphics#SNA_issues (so I didn't faced pixelated graphics, corrupt text, etc)

I just experienced Tearing after the mentioned update from 3 July 2019.

So, IF even uxa did not resove issues roll back to sna and tear free AND mainly report bug to bugzilla about it.


Well, I hope to have made a correct bug-report: https://bugs.freedesktop.org/show_bug.cgi?id=111386

If someone else (eg @ chris1 which reported the same issue here ) encountered the same, please confirm.
