I did some research last night on my cpu's power usage... came to the conclusion that it's the processor... it's at least over ten years old, so no worries. It's not your app's fault lol! I downloaded a demo made in unity and that worked fine so I'm thinking it has to be a latency issue steaming from mid tier internet connection and my Jurassic cpu... it only happens when I play larger apps in my chrome browser, and not just unity web games... it happens with godot, construct and gdevelop web games too.
