1620040 - Text artifacts when rendering a page from the Android developer reference

Status: RESOLVED INVALID

(Core :: Graphics: WebRender, defect, P3)

Description

[(No longer employed by Mozilla) Aaron Klotz]

Attachment: Screenshot

This is probably under the wrong component, but...

This seems easiest to reproduce if I right-click on a link and it into a new background tab. If I am looking at the tab and do a Ctrl+Shift+R, the artifacts go away. Note that a regular Ctrl+R does not make them go away.

Here is my about:support:

Comment 1

[Aria Beingessner [:Gankra]]

Couldn't reproduce this on the toronto windows testing machine with a GTX 950 (Maxwell). It's possible this is Pascal-specific (user has a Quadro P500), or just hard to trigger.

Almost certainly a Webrender bug and not specifically an issue with the Text component.

Serious enough that we should look into this more.

Comment 2

[Jessie [:jbonisteel] pls NI]

Rares, can you see if you can reproduce this issue?

Comment 3

[Rares Doghi, Desktop QA]

This issue is not related to WebRender at all, after installing every Add-on and then uninstalling each of them one by one, turns out uBlock origin is the cause of this issue.

This issue occurs with Webrender on and off in all versions of Firefox where uBlock origin is installed.

Just reach this page : https://developer.android.com/reference/java/util/concurrent/atomic/package-summary

If it does not happen right away open one of the links in a new tab, the repro rate is 100%.

Comment 4

[Jeff Muizelaar [:jrmuizel]]

Aaron, do you want to file a uBlock origin issue about this?

Comment 5

[(No longer employed by Mozilla) Aaron Klotz]

I haven't seen this in a couple of days, so a fix must have already landed. Thanks.
