1057665 - [OMTC] Repaint issue during and after scrolling in "Get Add-ons" panel

Status: RESOLVED WONTFIX

(Core :: Graphics: Layers, defect)

Description

[kenkon]

Attachment: Get Add-ons display issue.png

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:31.0) Gecko/20100101 Firefox/31.0 (Beta/Release)
Build ID: 20140716183446

Steps to reproduce:

1. Open about:addons in Aurora 33.0a2 (build 20140822004002)
2. Scroll...


Actual results:

1. Before scrolling, the "Get Add-ons" panel is displayed correctly.
2. While scrolling, the panel isn't properly repainted (see screenshot). After scrolling, it takes a few seconds before the panel finally repaints itself.


Expected results:

The panel should repaint itself correctly while scrolling.

Firefox 31 and 32 Beta8 are not affected. Maybe related to OMTC?

It's a bug with OMTC because I disabled layers.offmainthreadcomposition.enabled, restarted Aurora, and it fixed the problem.

Also, Firefox 32.0 Beta 8 is affected too if I enable layers.offmainthreadcomposition.enabled.

Did more testing today. My Intel-based laptop is not affected by this bug. However I was able to reproduce the bug on both of my desktops. The Graphics section of my other desktop, which is an Acer Aspire (AMD CPU + NVIDIA GPU), is:

Repaint issue seems gone in Firefox 33.0 Beta 3.
