Screentearing in latest Firefox 94.0 version

Support Xfce
1

I am using the latest version of Xfce Manjaro.

Problem:
With the latest 94.0 update from Firefox, I suddenly got annoying screentearing, when watching videos but also when scrolling websites. Screentearing is a visual artefact, often visible when the camera moves up and down or when you scroll up and down.

I am so glad that I found a simple solution, that I wanted to post it on the forum in case anyone else has got similar problems.

Solution:
Go to settings editor
Go to xfwm4 and select it.
Then scroll down to “vblank_mode” and select it.
Press edit and write “glx” in the “value” field.
Save and reboot.

I hope this solution will solve your screentearing problem as well…

Generally speaking the glx backend of the xfwm compositor is associated with screentearing.
(the newer ‘xpresent’ is generally preferred … and some people just ditch the compositor for another)
These settings are also extremely hardware or case dependent.

Ex:

If you use Intel graphics and you have already enabled “TearFree” option in Xorg config as described in Intel graphics#Tearing, then disable Synchronize drawing to the vertical blank option.

But glad this works for you. I will also leave this:
