[SOLVED] Diagonal and horizontal screen tearing only in Firefox

patresko · 2023-01-16 07:10:54

Using Mozilla Firefox 108.0.2, i3 and X.

Disabling picom doesn't fix the issue.

My /etc/X11/xorg.conf.d/20-intel.conf file:

Section "Device"
  Identifier "Intel Graphics"
  Driver "intel"
  Option "TearFree" "true"
  Option "TripleBuffer" "true"
EndSection

No other program produces the tearing, only Firefox. (Browsing in Chromium is smooth.)
Downgrading Firerox didn't help. It is worth mentioning that I didn't have this issue for like 2 years.
It only appeared around 6 weeks ago.

Use Wayland instead. X is fundamentally broken in respect of screen tearing.

Yeah, that solved the issue, but created some of it's own issues.

I think nm-applet icon didn't display properly or at all in swaybar.

And as I mentioned, I didn't have this issue for 2 years. Therefore it should be solvable without going full wayland.

You did have the problem but it was being masked by picom and/or the TearFree option in your X.Org configuration. Both "fixes" are dodgy hacks that induce unbearable (for me) lag.

I see now. Maybe I should consider going full wayland after all.

Thank you for your input.

Meanwhile I'm still open to suggestions regarding fix/workaround, however dirty it is.

I'd remove the 20-intel.conf file and use the modesetting driver instead (the default).

This.

Ftr: "diagonal" tearing is *not* "tearing".

You're seeing tesselation artifacts and the most likely cause is indeed the intel driver.

Ok, so I removed the 20-intel.conf file.

Should I now uninstall the xf86-video-intel driver and keep the mesa driver?

Also, the reason I had the 20-intel.conf file in the first place was this entry found on the wiki.

Yes.

keep the mesa driver?

https://archlinux.org/packages/extra/x8 … deo-intel/ lime most drivers depend on mesa.
You mean the modesetting driver and it's part of the xorg-server, so it'll remain.

This seems to have fixed the issue. Marking solved. Thank you all.
