Firefox quickly hotfixes multi-monitor glitches with Nvidia GPUs

Software is complicated—and I say that with the confident authority of someone who struggles to string a few lines of HTML together. But my point is, it’s not uncommon for software updates to cause unexpected problems, as is the case with the newest version of the Firefox browser running on PCs with Nvidia cards. But worry not! Mozilla has fixed it. With more software updates. That’s how this stuff works.
The latest version of Firefox (version 139.0.1) fixes a bug that caused artifacts to appear when rendering on Nvidia GPUs, but only when using a multiple-monitor setup, and only if those monitors were set to different refresh rates. It’s a rapid patch from Firefox 139.0, a major revision that dropped back on May 27th. According to Tom’s Hardware, the new update dropped a blocklist that caused issues if you had 60 FPS media running on a secondary monitor.
As Nvidia is still far and away the most popular vendor for dedicated desktop graphics cards, and multi-monitor setups are getting more and more popular, I can see why this sort of thing was immediately spotted. Because I have an Nvidia graphics card, and multiple monitors, which have different refresh rates, and I often watch video on the slower one. Mozilla has been having some issues lately, but it’s good to see them tackle an issue like this so quickly.
