1741174 - [Bug]: rendering broken in 94.1.2 (Moto X - Adreno 320)

Status: NEW

(Core :: Graphics, defect, P3)

Description

[Petru-Mugurel Lingurar [:petru]]

From github: https://github.com/mozilla-mobile/fenix/issues/22435.

Steps to reproduce

1. go to a website eg. en.wikipedia.org
2. scroll down the page

Expected behaviour

Text and images should be legible

Actual behaviour

Some images are corrupted or not drawn. Some text is replaced with incorrect characters (some not ASCII), sometimes overlapping. Scrolling backwards and forwards will change which text and images are rendered correctly, so after a while it may be possible to read the whole page.

Device name

Motorola Moto X

Android version

Android 5.1

Firefox release type

Firefox

Firefox version

94.1.2

Device logs

No response

Additional information

The same behaviour applies to Fennec 94.1.1. The previous release of Firefox and Fennec 93.1.0 work correctly.

Change performed by the Move to Bugzilla add-on.

I think Jamie managed to track this down in the github issue.

Not tracked down unfortunately, but did manage to confirm a (fairly surprising) regression range

Hi Jamie, any updates on this?

I ordered a Moto X device, but it arrived running Android 4.4 and it cannot find the 5.0 update. So no luck there.

I've ordered a Nexus 4 instead, which has the same GPU and is easier to flash different android versions. Hopefully it will have a similar enough driver version to reproduce the issue.

Hi Jamie, any luck with the Nexus 4?

Comment 8

[Jamie Nicol [:jnicol]]

Unfortunately not. Nor with a Samsung Galaxy S4 or a Moto X as the original reporter had.

Tested steps using Fx97.1 on OnePlus 8 (Android 11), and could not reproduce.
