For some time I’ve noticed artifacts when playing video from streaming services like Netflix and Amazon and I’ve come to realize that at least some of it is content from other windows I have open. Below is Amazon playing a video and the text Explorer Privately is from the Tor Browser homepage.
This is a screenshot with increased exposure.
I have Kubuntu 20.04.2 with Nvidia driver 460.73.01 and I use Firefox 88.0.
I don’t notice this overlay when playing back video through VLC or from YouTube. When I stop playback the overlay disappears.
Has anyone seen this, might it be an NVIDIA issue or even a security issue? DRM eavesdropping on us?
I’ve never noticed this, but I’m for sure going to keep an eye out for it
Was the writing that shows through light text on a dark background, or was it inverted?

Yeah, the text is white and the background is purpleish like the red onion in the tor browser logo.
You’re still getting Tier 1 Widevine because it’s Linux and everything is at 480p and below. Means Disney+ will not work.
This seems to be a GPU rendering issue if video acceleration for decode is on. Try turning off accelerated decode.

Still getting it when I uncheck “Use hardware acceleration when available” and restart firefox.
I also tried it on another PC with similar results, granted both have Nvidia cards and Kubuntu
It is possible the GPU rendering engine got screwed up in later Firefoxes.
Try layers.acceleration.force-enabled = 0
and layers.acceleration.disabled = 1
If those don’t work, you might want to print out your about:support
or downgrade the driver.
