    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.

          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
