[Solved] Video glitching and rough scrolling in Firefox
Graphics Card : Intel Corporation Skylake GT2 [HD Graphics 520]
Display Server : X
Driver : xf86-video-intel
I've had this problem since the day one of installing Arch. In Firefox, when I go in fullscreen mode of a Youtube video the the glitchy bars are more subtle and appear more frequently in faster frame transitions. Also when I even scroll through a page in this browser I see a bar, that is disturbing, halfway of the screen. How do I fix this ?

Graphics card, used driver, general environment, xorg or wayland?
Moving to NC...

Are you talking about vsync? Use a compositor which uses libxpresent (works perfectly on at least nouveau & intel).
Arch is surprisingly behind the times, on this.

This is the exact effect I'm talking about. This happens too much while watching videos on youtube, especially fullscreen mode, on Firefox.

Yes that happens if you don't have a vsyncing compositor, post details on your setup.
xf86-video-intel has a xorg option TearFree to alleviate this even on non composited desktops, however it might introduce some other issues (or at least used to, been a while since I've used it)

But /etc/X11/xorg.conf.d/20-intel.conf file is missing so I can't set TearFree to True. What do I do ?

Compton doesn't use libxpresent.

Regarding the file, you can create it, if it doesn't exist it will simply use the default options.
