Could be something peculiar to Nvidia GPUs, or maybe it’s just Firefox, but I never see this colour anywhere else, only when something causes a glitch in the rendering of video content. Sometimes it’s not just the video player that goes green, but the entire viewport of the browser window. I’m mainly curious why it’s that colour, rather than just black or white or something like that.
Cheers!
Trees appear green because they absorb red and blue light while reflecting green light. Maybe your TV is photosynthesising ¯\_(ツ)_/¯ I just wanted to add to the list of unhelpful answers
Just that monitors don’t redlect light, they emit light, and rules change
I don’t have that problem, because I don’t use windows
I’ve seen it on linux, too.
You are being downvoted because your comment is rude, irrelevant, and neither helpful or funny
No, no, it can only be because of fanboys
I hate windows and never willingly use it but I downvoted you for being an idiot, just so you know
I wouldn’t have expected this comment to be downvoted on lemmy. No valuation, just an observation.
I assume: If comment would have pointed out that this is in fact not a hardware related behavior but depends on software and doesn’t happen on Linux, down-voting wouldn’t have happened.
I’ve had green screens show up on Bazzite while restarting or if steam crashes(rare). All amd system as well.
Maybe it’s some sort of chroma keying?
It’s not
I recall seeing such green on screenshots of DRM protected video on iOS (back when I still had Netflix installed)
Replying to people with an AI answer is extremely disrespectful, even more so with a screenshot of that answer. The fuck do you not understand that?
I haven’t seen this exact screen, but since there’s very little help in this thread so far, I’ll speculate.
I’ve seen plenty of single solid color screens that turned out to be “fuck you i didn’t like something, have a plain color instead of your image” from some piece of Digital Rights Management software.
If it is DRM, the two approaches I’m aware of are:
This happens when I try HW decoding on VLC on an old AMD card, the video is the wrong aspect ratio with letterbox bars of this color. At first I thought it’s some default in the ITU-R BT.709 (YCbCr) colorspace used in most video codecs but those RGB values map to an uneven 55, 106, 100…
The former flag of Libya
I have never had such a freakout. It generally just works.
Well something in the graphics driver is breaking, so that color is probably unique to your hardware and drivers
This happens to me as well when something goes wrong with video in Firefox. Perhaps something unique with software?
My calculations say that YCbCr(0, 0, 0), which is presumably the default state of the video framebuffer, will become RGB(0, 73, 0) after ITU Rec.609 colorspace conversion and gamma correction. Not exact but very close, the video might just be using a slightly different color profile from the standard.

The Video itself is rendered off screen in a special area of memory, then the browser simply uses a predefined color to tell the driver where to display the video. The driver then takes care of things like stretching to fit etc.
It’s not actually that shade typically, and you are just seeing a side effect of the glitch.

That doesn’t really answer the question though. Obviously it’s the side effect of some kind of glitch, but why is it always this green, why not orange or blue

It’s the green screen which allows blending, melding, switching and superimposing layers. You see, the way it works is that I don’t know, but it got you reading this far and wasted a few moments of your time which could have been spent doing something else, like gardening.
But really the answer is probably because it’s very nearly in the middle of the VGA color palette.

Probably causes less eye strain, while being noticeable.

I’ve never really thought about what happens to data that the system fetches over the internet. So, just as if it would’ve been stored in permanent storage locally, it’s loaded into system memory, which then “serves” it back to the browser? In my beginner head, it then looks like this: YouTube -> system memory -> browser/media player
ripcord@lemmy.world 3 weeks ago
Correct. Eventually millions of very very tiny squirrels then eat the data once it is discarded.
I’m simplifying a bit, but that is generally how it works.

it doesn’t just update the dom via x/y? currently making an 8080 emu and am not using browser yet but may. also tell me more about your instance?

anarchist.nexus is a piefed-instance in the anarchist flotilla.
