A long long LOOOONG time ago I tried to screenshot a video in windows media player and the screenshot still changed when I moved or played the video. I often wonder if that was a fever dream or just some weird shit that was happening with really early tech. I remember being so mad because I just wanted a screenshot of a scene in the video and it wouldn’t work lol
Not a fever dream, I remember this, too. You basically got a “transparent” image through which you could see the rendered live (or game, as it happened with those, too). As soon as you closed the video player/game, or saved and reloaded the image, the effect was gone and you were stuck with a… I think it was just a black image?
I think it just remapped the memory of the video process, but I could be way off…
Back then, there was less hardware acceleration for the regular desktop stuff. Probably it just copied the data from the software rendering, and there it just defined that this part of the screen was hardware accelerated and this region pointed to vram instead of regular RAM.
