1436420 - Webrender: Corrupted Activity Stream Rendering (transform && position-fixed bug?)

Status: RESOLVED DUPLICATE of bug 1435143

(Core :: Graphics: WebRender, enhancement)

Description

[Aria Beingessner [:Gankra]]

If you create a new tab and shrink the height of your window, the settings menu for the activity stream will suddenly appear, even though it should still be translated off the side of the screen.

I've reduced the problematic HTML down in the attached file. Notably:

transform: translateX(x%); where x > 0
overlow-y: auto;
offset-inline-end: 0;
position: fixed;

seems to misposition its contents (although curiously the background color is drawn correctly)

Haven't been able to make a capture, as capturing always crashes on my machine right now.

(translateX + position:fixed also played a role in bug 1435143. A try build is on the way.)
