No crash on my system, unfortunately. |

There is an issue with a backtrace similar to yours #1672. If there is no backtrace, but gala still crashes, it would be helpful if you could debug gala manually. Please install After that you can |

Well, thank you for letting me know, it seems you successfully patched a segfault that was occurring in gala, which might not have been the problem here, and possibly the issue remaining is system-specific on my end. If I feel the need to play CS2, I'll probably switch back to Fedora, since the newer packages there make it a better choice for gaming. Thank you for the patch, the competent and friendly communication and giving it a test on your end. <3 |

Ha, that was a bit too early of a reply, I will try to debug it for you. |

Here's the gdb.txt, but please note that I could not run bt and exit as it was kinda stuck, I had to interrupt it with CTRL+C in order to have a prompt again. Starting program: /usr/bin/gala -r --display=:0 Thread 1 "gala" received signal SIGINT, Interrupt. |

I have more helpful output for you, but that required me to make photos of the screen, as it would not be written to the gdb.txt. There's the critical error you might be looking for. |

Hm... if you had to interrupt the gdb with Ctrl+C that means that gala definitely no longer crashes. But the issue it still there... Can you make a photo of desktop when this happens please? Also, just to be sure about touchegg, disable it And the last I can think of, try updating the drivers, e.g. using this ppa https://launchpad.net/~kisak/+archive/ubuntu/turtle/? |

This is what I get when I exit the game: And I can press the left super key to bring at least parts of the desktop back, like the wingpanel. But windows that were open prior to that, like the Steam client or LibreWolf or Telegram are gone - you can still see them active in the dock though: Going to test disabling touchegg and geoclue now, as well as updating the drivers as you suggested. |

Neither masking and disabling both touchegg and geoclue, nor updating the drivers from the ppa did change the issue. I suspect that Valve does something on exiting the game that the Pantheon desktop doesn't like / account for. And / or that might be somewhat system specific. Of course, I verified the game files multiple times and even cleared the download cache and shader cache with Steam's builtin settings, btw. |

To confirm my suspicion that the issue is pantheon related, I have bastardized my elementary installation by installing the plasma desktop. The game exits just fine there. (It doesn't start with Proton either, but that's a separate issue) I think in order to solve this, you would need to contact valve and get information on how they do the window management / giving control back to the desktop, what function calls for which frameworks they are using and it's probably something not implemented in pantheon or not properly implemented on the AMD side of things... or maybe just bad exit handling in CS2 and a bug on their end. :3 |

Well, as you might imagine, all this tinkering and installing plasma have borked pantheon a bit and honestly, I didn't have the best impression of elementary's technical state in the last few weeks. A lot of little things about the experience have been lacking polish, from updating via the AppCenter over some of the apps like Movies. Which is sad to see. It appears that the internal issues of the team did have some negative effects on the quality of the distro, at least for a while. I'll check it out again in the future, but for now, I think I just switch back to Fedora or Ubuntu. I just want a system that works, looks somewhat decent and is good at gaming. Thank you for your efforts and kind communication. |

So, the new Counter Strike 2 is out, and when exiting the game, I land on a grey screen with a mouse cursor. According to dmesg, it's a sefault in libmutter:
[] gala[5206]: segfault at ffffffffffffff08 ip 00007fa6dda69efb sp 00007ffee2dfd278 error 5 in libmutter-10.so.0.0.0[7fa6dda49000+144000] likely on CPU 8 (core 0, socket 0)
[] Code: 0f 1e fa 48 8b 07 ff a0 28 01 00 00 0f 1f 00 f3 0f 1e fa e9 a7 df 11 00 0f 1f 80 00 00 00 00 f3 0f 1e fa 48 63 05 4d 2b 1b 00 <48> 8b 44 38 08 c3 66 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 40 00 f3
I don't know if posting this here will be of any use, but since it is such a popular game, you might wanna see if it's the game's fault or on the pantheon side. :)
