On reddit someone suggested to use ripcord instead. It has an appimage, so also on Solus it should run fine. I haven't tried myself, but just in case it's a nice alternative for anyone having these discord issues.
Discord randomly shutting down
As I said, it happens quite a lot. So here's my output:
Crash dump id: 69e266cd-4618-4a21-847f-c3bc3244ecb9
Segmentation faultIt's the same as @laky 's output, but I got an ID. Does anyone know where I can find the crash dump?
sgvd ooh I like this, thanks for the heads-up!
Please submit your feedback about Discord crashes to them, they're the developers and it is a proprietary application, so even if we got a crash dunp we wouldn't be able to fix the application itself.
I've read somewhere on forums about this problem, and one of the comments was to try installing flatpaks version of discord, is that possible here on Solus?
- Edited
yup! I might try that again.
https://www.flatpak.org/setup/Solus/
After you set it up (follow the directions on that link) then just flatpak search discord should tell you the exact name.
- Edited
Snoober I did something similar for wine-staging repository might actually try install flatpaks repo and try it out..Btw , how do you mean again? You already had flatpaks discord installed or was it something els you needed it for?
Edit: Okay I got this
Application ID Version Branch Remotes Description
com.discordapp.Discord 0.0.10 stable flathub Chat client
Now how did you install it?
Edit2: Nvm , I managed to install it now i am going to test it out . Is it not possible to run it from terminal anymore after you install the flatpak version? running discord in terminal does nothing now.
I noticed the issue too. :/

I got an answer from Discord team via email i send them. This is what they replied:
I'm very sorry to hear that you're having trouble using the Discord app while playing games within your Linux machine.
Could you please try to completely uninstall the client and reinstall it through the use of
sudo make uninstallin your distro's terminal?If you continue to experience this same issue with our updater upon reinstall, let's see if the issue persists in our Public Test Build. You can grab our PTB client here!
If you're using Deb: https://discordapp.com/api/download/ptb?platform=linux&format=deb
If you're using Tar.gz: https://discordapp.com/api/download/ptb?platform=linux&format=tar.gzHere's also Github with some common fixes to some of the issues in the Linux version https://github.com/simoniz0r/Discord-Linux-Client-Issues.
Give these steps a shot and let me know how it goes.
I wonder is it safe to use this tar.gz and compile it in Solus, in other words how would this work?
Edit: Safe thing aside, i have run it and going to test it from there.
18 days later
I can confirm Discord crashes incessantly and dozens of other people have come out of the woodwork to report it, which is a Discord problem. I am posting here to say @laky that I stopped the crashing on my system by turning ON 'Minimize to tray' (ENABLE). lol Hope that narrows down workarounding on Solus.

JohannPopper Hey funny thing is that probably won't stop it from crashing, but the most recant info about a workaround that i got involves couple more things to be disabled atleast it did for me. If you get anymore crashes try this:
Voice & Video - For INPUT SENSITIVITY and disable "Automatically detemine input sensitivity." (set it yourself)
"OpenH264 Video Codec provided by Cisco System, Inc." (disable)
"H.246 Hardware Acceleration" (disable)
"Enable Quality of Service High Packet Priority" (disable)Notifications - "Enable Desktop Notifications" (disable)
"Enable Unread Message Badge"(disable)Game Activity - (have this disabled at all times)
Streamer Mode - "Enable Streamer Mode" (disable)
"Automatically Enable/Disable" (disable)
"Disable Notifications" (disable)Hope it helps! 
(Notifications having disabled is 99% of the problem which fixes it,well maybe...)
Edit: This is just my settings not sure is all of this needed, 'Minimize to tray' is enabled for me too but that alone didn't fixed it.
Just want to state that I am not installing the discord app once it is fixed. I am using Ripcord now and my friends asked "are you using Windows again? The sound is much better now".
For context:
I had a lot of trouble with sound quality with Discord since I started with Linux (12+ months ago). Steam voice chat was the goto option when it was just too bad for my pals to content with me in the Discord channel.

I've had the same issue for awhile. Ripcord works a lot better, but not as stable as in a browser and no video call capability. Just found this claiming that it might have to do with the package "libappindicator", so it seems it might be related to notifications. People say uninstalling that package might help but I don't really know if that's safe.
