    Curiously, I switched to modesetting just because the tearing issue: on my Broadwell (i5-5200u) laptop (Arch+ x11 GNOME) the situation was horrible, and modesetting fixed it.

    NB: I know, things are complex and different on each hardware and software combination, in fact I noticed tearing only on fullscreen (i.e. here https://youtu.be/32zW2hTYm74?t=400)

    Probably because tearing is supposed to be solved by the compositor and not by Xorg itself.

    I didn't even know there was another driver for Intel...

    might "present extention" has fixed at xrog-server 1.20.9~10 so recommend to use newest.
    I'm using reverse PRIME when notebook is on power (everything is running on Nvidia, iGPU only draws the picture) and I can disable Vsync in this case. And it seems KWin does not support xpresent, I found only Trello card about it dating 2014. So to use notebook with iGPU comfortably I have to use kwin-lowlatency. And I cannot use video-intel because it is bugging with games.

    I did use xf86-video-intel until recently, I noticed that opening certain game (Half Life Lost Coast for example) caused the whole of X to fall over

    https://gitlab.freedesktop.org/xorg/...l/-/issues/204

    A commit was added which was different to the one I tested, but ended up not fixing the issue

    So using xf86-video-modesetting until it's sorted

    I too still use xf86-video-intel on my Intel systems (Haswell, Baytrail, Apollo Lake, Coffee Lake). It works great with TearFree, so I haven't had any reason to switch away.

    I've got a laptop with Intel HD Graphics 520 (Skylake, Gen9), and Ubuntu 20.04, so this update would potentially apply to me (and I've observed lots of annoying tearing).

    I see that for the package "xserver-xorg-video-intel" (which didn't get installed by default), the current version available to apt is 2:2.99.917+git20200226-1. When I go into the GUI for "Software & Updates", under the "Additional Drivers" tab, there are "No additional drivers available" when it checks.

    Just saying.

    I am still using xf86-video-intel on my Haswell desktop, because otherwise screensharing in Chromium, as well as x11vnc, has a lot of glitches like randomly showing my wallpaper instead of the actual screen contents. The desktop environment is Cinnamon.
