Your system information

• System information from steam (Steam -> Help -> System Information) in a gist: https://gist.github.com/s6fty/7417b18e3cd9abfbc70453bdc3659c41
• Have you checked for system updates?: Yes

Please describe your issue in as much detail as possible:

When i alt-tab it should show me the program that im alt-tabbing but instead my monitor signal cuts out and i need to restart my computer or switch to tty1 and restart lightdm which i can see CS2 is still on.

update: it only cuts signal when on matchmaking, on practice mode i needed to alt tab a few times and then it worked as intended but when i load into matchmaking (deathmatch/competitive) it crashes no matter what.

Steps for reproducing this issue:

1. start the game
2. load into matchmaking
3. alt-tab
4. signal cut

Hello @s6fty, can you check if dmesg or the system logs have any hints related to this issue?

https://gist.github.com/s6fty/9e66157705453e8bc27ff0cbb0c3e193 this is dump of dmesg and journalctl, only thing that hints to signal loss is Sep 29 17:06:19 s6fty acpid[711]: client 870[0:0] has disconnected

Thanks, skimming over the journal, looks like Sep 28 18:33:45 s6fty kernel: NVRM: Xid (PCI:0000:29:00): 8, pid=4621, name=cs2, Channel 0000002f might be interesting. Apparently that means "GPU stopped processing" from https://docs.nvidia.com/deploy/pdf/XID_Errors.pdf.

It may be worthwhile to also mention this issue to your video driver vendor.

Hey, any update on this? I have the same Issue, but I don't even need to be in a game. When starting the game it already does this, and whenever I alt+tab.

@Straylx i switched to xfce, its gone now. do you use cinnamon too? its not fixed, it still continues.

@s6fty I'm on Windows 11... But I recently turned off HDR and it kind of fixed the issue.
