Briefly describe your issue below:
After upgrade to kernel 5.3xxx I had horizontal screen tearing while browsing internet, playing videos…
While searching for answers on net I found this potentially solution:
I found some solution putting 20-intel.conf file in /etc/X11/xorg.conf.d/ like suggested in link above and added all options, because basic settings didn’t gave me good results, and Firefox has issues -there were no bookmarks, addons, customizations…
Section “Device”
Identifier “Intel Graphics”
Driver “intel”
Option “TearFree” “true”
Option “AccelMethod” “uxa”
Option “TripleBuffer” “true”
EndSection
This solves my problem but created another -after screen goes to sleep I did not manage to back to screen -I can see only mouse but screen was black…
After that I find some texts about gpu compositors and other window managers, and finally I read about Compton GPU compositor and installed it and activated it trough “Mate Tweak” and changed in Windows manager from Marco (Adaptive compositor)-default to Marco (Compton GPU compositor).
And now I have zero screen tearing 
I hope that some will find this useful…
Just to mention that with kernel 5.2 screen tearing was not so obvious like with newest 5.3
