Introduction
Mozilla has swiftly released an emergency update, Firefox 139.0.1, to address critical graphical issues affecting users with NVIDIA GPUs. This update follows complaints from users regarding flickering videos and artifacts on various websites. Discover how this fix restores functionality and protects your browsing experience.
What Caused the Graphical Issues in Firefox 139?
The Bug Origin
The troubles began with the release of Firefox version 139 on May 27, which introduced features like Full-Page Translations. However, this version unintentionally enabled a specific behavior in DirectComposition that led to graphical artifacts when users browsed with NVIDIA graphics cards on Windows 10.
Many users discussed these issues on platforms like Reddit, noting that they experienced video flickering and page corruption on popular sites, including Instagram.
Understanding DirectComposition in Firefox
DirectComposition, a Windows API used for rendering graphics, was previously restricted by a blocklist in Firefox to prevent issues in multi-refresh rate setups. Unfortunately, the removal of this blocklist in version 139 exposed a graphics driver bug, causing visual artifacts when displaying content across monitors with varying refresh rates.
When users played 60 FPS videos on a 60 Hz monitor while navigating on a high-refresh-rate monitor, the issues became evident. The resulting video buffer leaks created noticeable flickers and artifacts during page refreshes.
How Did Mozilla Address the Problems?
Release of Firefox 139.0.1
In response to these persistent issues, Mozilla rolled out Firefox 139.0.1, re-implementing the blocklist that previously protected users from these graphical bugs. According to their official release notes, the update “fixed graphics corruption with certain NVIDIA graphics adapters and multiple monitors running at mixed refresh rates.”
Installation Instructions for the Update
To update your browser to Firefox 139.0.1:
- Open Firefox.
- Go to Settings.
- Click on Check for Updates.
This should resolve the flickering issues experienced by users.
Unique Tip for Cyber Security Awareness
