Discord 0.0.12 very laggy and spawns too many processes

I have been using Discord on Arch for a few months now and lately it has become very laggy. When I first start it, it's not so bad. It's not as snappy as what I was used to in my previous experiences with Ubuntu, but it's nothing to complain about.
However, after a couple hours the user interface becomes extremely laggy and slow and it's barely usable. The sound is fine though, so at first I thought it was some kind of memory leak. So I ran top and got something like this:

$top

The CPU usage is quite high. The memory usage is ok I guess.
Also I was aware of the fact that Discord uses different processes. However, when I run

killall -i Discord

immediately after I have opened Discord, it kills three processes but when I run the command after it has started lagging it kills seven or eight processes. Is this normal?
The same happens with discord-canary and discord-ptb.
I don't know if it has something to do with the desktop environment but I'm using GNOME 3.
I have read older issue reports that suggested there was some kind of problem with the video codecs. Is it possible the issue is something related to that?
Thanks in advance.
