Screen tearing for UHD 620

I am having screen tears on my laptop (Thinkpad T490s) in all applications (Steam client, discord, firefox)

I use i3-gaps as my window manager, compton is my compositor

.config/i3/config

exec_always compton -f --vsync

neofetch tells me that my graphics card is Intel WhiskeyLake-U GT2 UHD Graphics 620.

My /etc/X11/xorg.conf.d/20-intel.conf is

Section "Device"
  Identifier "Intel Graphics"
  Driver "intel"
  Option "TearFree" "true"
  Option "TripleBuffer" "true"
EndSection

(The wiki suggested that I put the line

Option      "AccelMethod"  "uxa" 

into that config, but doing so slowed down the desktop experience immensely)

I've also installed xf86-video-intel

Please let me know if I am doing something wrong or if any other info is needed to know the fix.

Re: Screen tearing for UHD 620

To avoid tearing, at least in latest firefox versions, a compositor needs to be running.
In games this isn't necessary.
Have you tried to uninstall xf86-video-intel and just delete etc/X11/xorg.conf.d/20-intel.conf?

Looks like I forgot to mention that I was using compton as my compositor.

Installing xf86-video-intel and deleting the conf will not help, both were attempted fixes for the problem.

the current compton settings are compton -f --vsync, do you think that this might be an issue?

Re: Screen tearing for UHD 620

I suggested you to UNinstall intel driver (and reboot).
I'm not familiar with compton; do games and videos through mpv tear in fullscreen if you disable compton?
Are you driving a single monitor?

Re: Screen tearing for UHD 620

Oops, "Installing the driver" was supposed to be "Uninstalling the driver".

Anyways, I tried uninstalling the driver and deleting the config. Tearing persisted.

turned off compton:

Halflife had screen tears
mpv had screen tears
firefox had screen tears

I am driving one monitor, the one attached to my laptop.

Re: Screen tearing for UHD 620

What's the output of:
glxinfo -B
cat /var/log/Xorg.0.log
cat /proc/cmdline
?
