Ah yes. Semi-modern PC shouldn't have trouble... Download sizes shouldn't be a problem... Do you realize that you are essentially running a supercomputer? And that this supercomputer is struglling to display even the simplest things? Slack's CPU usage shoots up to 20% of cpu to display a single animated reaction to a post. Run a few of those "shouldn't have trouble" in parallel, and suddenly a computer that can run a 4k next-gen Unreal shooter at 60fps struggles to even maintain cursor latency.
