I’ve got a new 7840HS laptop, and have noticed some stability issues with games on Steam under Proton that run fine on my desktop with a 5700xt. I know the 7840 line is pretty new and not a lot out in the world yet, but has anyone noticed similar issues?
Next time you run into stability issues, you should check in
journalctl -eand see what error messages pop up. It is hard to help you without additional info.
