1409564 - There seems to be a gray overlay that appears when scrolling through the page

Status: RESOLVED FIXED

(Core :: Graphics: WebRender, defect, P1)

Description

[Asif Youssuff]

Attachment: webrender-vs-nightly.png

Steps to reproduce:

Enable:

turn on gfx.webrender.enabled
turn on gfx.webrendest.enabled
turn on gfx.webrender.layers-free
turn on gfx.webrender.blob-images
turn on layers.acceleration.force-enabled

1. Navigate to  http://www.seemolly.com/
2. Scroll down until you see "My Skills"


Actual results:

There's a gray overlay over the images and text.


Expected results:

No gray overlay.

See screenshot for what it looks like.

[Aria Beingessner [:Gankra]]

Can't seem to reproduce on the latest macos nightly. Might be linux-specific?

That website has two issues that are the same in WR/non-WR:
a) slow pageload
b) the bg behind "MOLLY SAUNDERS" flickers once.

Remaining issue:
When you scroll down+up and the background of MOLLY SAUNDERS is about to leave/re-entering the screen at the top or at the bottom there is a flickering black bar on the edge of the viewport.

I additionally discovered that the flickering black bar at the bottom of "MOLLY SAUNDERS" can get permanent and grows if I resize the window. But it goes away if I scroll to the bottom and up.

The website looks totally fine on my new linux machine, can someone who was reproducing this confirm it's fixed?

Oh, unexpected: I managed to reproduce the crazy bug with a fresh non-WR profile. Sorry!
Then we can mark this as fixed by bug 1426116.
