Total system freeze since last stable update

Hi everyone!

So, since the last stable update my system freezes suddenly and it’s completely unresponsive to any input and it’s only fixed by a reset.
Now, I think I isolated the problem: it only happens when I’m playing Hearthstone via Lutris, so from time to time my system freezes midgame.
Hearthstone it’s not my main concern, if I have to give it up to have a stable system so be it, but I want to know what is causing the issue and I’m not competent enough to find/understand the information from the journal so I’m asking for help.
It all was just fine before the last update and I think it’s very strange that it affects only that application.

Again, I’m not asking for support on lutris/hearthstone, I just want to know how to isolate and track down what the issue is and maybe learn how to troubleshoot this kind of problems in the future!
Thank you in advance and a have a great day!

FWIW I also experienced a freeze after the update. KDE but 5.10 kernel. It happened as I was changing the audio output device in discord. Since you mentioned you were playing a game, I would not be surprised to find out it has something do with audio.

Hi @patrick,
That is strange indeed, I’ll look more into that!
I tried with kernel 5.10 and the issue didn’t present itself, but gaming performance on that kernel are terrible for now, at least for me and I didn’t test it extensively.
I need every last bit of power I can squeeze from my poor old core i3 :joy:
Thank you!
