```suggestion
 xdg-utils webrtc-audio-processing libXScrnSaver"
```
I went through all the dependencies of `gst-plugins-bad1`, and the missing one is `libXScrnSaver`.

further confirmed with `strace`:
```
$ strace -Z -ff -o discord.log Discord
$ grep libXss discord.log.* | wc -l
384
$ sudo xbps-install libXScrnSaver
$ strace -Z -ff -o discord-xss.log Discord
$ grep libXss discord-xss.log.* | wc -l
1
```
