Mosila rolled out an emergency Firefox 139.0.1 update after Tuesday’s release, leading to graphical artifacts on PC with NVidia GPU.
Firefox 139 was sent with features such as full-hit translation on 27 May, but also caused graphical artifacts when browsing the web in the firefox.
One in Redit threadMany firefox users complained that the video would be flicker or flash. This problem also affects webpages, including sites such as Instagram.
Mosila has quickly identified the root cause and sent a hotfix with V139.0.1.
One in Post on BagjilaMosila confirmed that Firefox 139 re -enabled a specific directcomposition path behavior, causing these issues.
In the previous release, the Firefox laid a block list, which prevented the Firefox from using the direct competition on the mixed-Rifresh Nvidia setup.
Unfortunately, the block list was removed with Firefox 139, and it allowed the browser to use directcomposition, which highlighted a graphics driver bug on the NVIDIA card under Windows 10.
When you play 60 FPS videos on 60 Hz Monitor and then scroll or hover on the content on a high-rafresh monitor, parts of the video buffer leak to another window.
Wherever the page is resumed, it shows as shining artifacts or corruption. The problem is not accompanied by 30 FPS content because the frame timing line is both with fresh rates.
Single-monitor or AMD/Intel setups were not affected by these issues.
It is also worth noting that directcomposition is not a problem, but the implementation of Mozilla struggles with some GPU.
“Currently only one thing that makes the firefox special in this regard, it is that it uses Windows Direct Composition (surfaces instead of swapchan) in a certain way for the majority of web materials …” A firefox developer has mentioned in one Post on Bagjila,
“We have a new code path (as it is called a layer composer) that should be available for testing at night in the firefox in the coming weeks, if all go well, we will be interested in testing that when it is ready on the same computer, on the same computer, to verify whether there is any clutching with other browsers.”
Firefox 139 Mozilla Fixed artifacts
