Why is xdg-mime using so much CPU?

Question

Every time I start Discord, I see four processes called xdg-mime appear in the System Monitor, each consistently using somewhere between 20-25% of a CPU.

What are these processes, and what are they doing? It seems odd that they're using so much more processing power than discord itself is.

Answer 1

I had the same problem, as did the people here.

One of them posted this link to a workaround to our problem.

Type which xdg-mime in the terminal. If the output is /usr/bin/xdg-mime then create a file called xdg-mime in /usr/local/bin/, containing the following:

#!/bin/bash
if [[ "$@" == *"x-scheme-handler/discord"* ]]; then
    /usr/bin/true
else
    /usr/bin/xdg-mime $@
fi

Make the file executable.

If xdg-mime is not installed at /usr/bin/ then, instead, report back and I will try to help.

I hope the people at Discord fix the problem for real, but for now, this is good enough.
