    Graphical corruption on Intel graphics has plagued my experience with various laptops and occasional desktop in Linux for the past ten years. If this can help them figure out what the problem is, even if it causes some performance loss, I'm all for it.

      Really? I’m using Ivy Bridge and Broadwell graphics chipsets and have no problems. Wayland makes it even better.

        Most likely "xf86-video-intel" is to blame here...
        Just remove it & be done with your corruption problems!
        The 'modesetting' driver built into the X.Org-Server will automagically take over; you don't have to do anything else on your own.

        Incidentally, I was seeing tearing with mpv on Intel's Gen7 graphics, and traced down the problem to "xf86-video-intel". (Which is dead, by the way...)

          I'm going to echo the other guy called Linuxx on saying that you probably just need to nuke xf86-video-intel and use the generic modesetting driver instead. Similar experience, it's baaaaad.

            Yeah, I don't think xf86-video-intel even supports my kabylake system. On modesetting.
            I'm having tearing issues (intermittently) and corruption issues. Wayland is a lot less stable, and I get a LOT more glitches, so I'm still on Xorg for now.
