I managed to solve it by removing xf86-video-intel which was installed by default. Had read in Archwiki that some users have problems with this driver installed. Tested with some screen tearing videos on Youtube and confirmed its gone now.
In all honesty, I wanted to try your method but I couldn’t make head or tails out of it (I’m a very fresh noob).
I saw a number of nVidia and AMD screen tearing posts but couldn’t find one on Intel so I thought I register an account here and ask.
Machine: Dell XPS 13(9360)
GPU: HD620 (Kaby Lake)
Linux Knowledge: NIL (or close to NIL)
Drivers: MESA and Intel Vulkan drivers(17.1.5-1)
Problem: Noticeable screen tearing when browsing (Firefox). Search Wiki and saw some mention of installing Intel drivers. MESA was already pre-installed so I tried Vulkan (which is really supposed for gaming purposes I guess) and to no avail.
I am really new into Linux (hate the telemetry and wish to break free from Microsoft) but not good in CLI at all.
Hope someone can shed some light.
Appreciate any kindness for a noob.
