Okay I'd like to believe that I'm relatively understanding of how my laptop works in parts enough to work on it if I have to (from the software side, hardware is a bit trickier).
What would make a Debian machine (or Linux, I've tried a KDE Neon live boot and got the same issue) to choke whenever video playback in _any_ application occurs? I get this with Zoom, Firefox (via Jitsi, Google Meet, YouTube etc).
32 GB of RAM, an 11th Gen Intel i5 should not be moving like this. I can build Firefox on here (though it takes quite some time) and Rust (not as long), but if I were to hold on a video call, within a minute, I'm getting 4fps video with wild audio lag.
