[screen tearing] xf86-video-intel or compositor?

hey folks. i have a cozy minimal openbox setup on an nvidia optimus(skylake+nvidia mx150) laptop. it's currently rocking on mesa+prime-run flawlessly. however the screen tears on scrolling in gedit or firefox and playing videos in mpv.

google tells me there's two possible solutions: installing xf86-video-intel and add "tearfree" option to config file(but it has performance downsides) or just go with a compositor(not sure if it's a real solution)

how'd you deal with the tearing issue guys?

cheers

I'd personally go with a compositor, xf86-video-intel is not well maintained and has a bunch of other potential issues. The standard modesetting driver is also better tested and confirmed to be working with prime-run than xf86-video-intel

which compositor, if you don't mind me asking

I use KDE/Kwin so don't have much experience with other standalone options, but picom is an often mentioned option here

nb. that xrender cannot really sync to vblank, picom offers a hybrid mode where the vblank signal is obtained via glx and the painting is done in render but I doubt that's reliable.
xcompmgr is render only.

"tearfree" will ultimately require more than a compositor, the client must not send a torn image.
for mpv try

mpv -vo=gpu --video-sync=display-resample ~/certainlynotaporn.mp4
