1663202 - Whole facebook page flickers when scrolling through news feed

Status: UNCONFIRMED

(Core :: Graphics, defect)

Description

[Clemens Eisserer]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:82.0) Gecko/20100101 Firefox/82.0

Steps to reproduce:

• after logging in at facebook.com I was informed my account was migrated to the new react based frontend

Actual results:

When scrolling the newsfeed, the whole facebook page flickers which is rather irritating and ugly: https://youtu.be/ieJ3yOl5f7Q

Keeping in mind facebook.com is such a high traffic / widely used page, I thought reporting it would be a good idea.

I see the flicker with:

• The "classic" OpenGL backend
• The "classic" Basic (skia) backend
• WebRender (Software) - despite the flicker, this backend is also extremly slow

My system is a HP Elitebook 2540p (1st gen Core i5, Arrandale) running Linux.

Expected results:

The page should scroll withought flicker and fast, just like with Chrome.

in the meantime I switched to a new laptop which supports webrender - where is see the flicker too.
however beacause the new machine paints way faster, it is far less distracting.

@Clemens, are you still seeing this? I came here after noticing something similar.
