What steps will reproduce the problem?

My screen locks after 5 minutes of inactivity. I noticed that if I left my game running and go afk, when I return, awake my screen and enter my password I find my game crashed. I tried with hello-world, the same stacktrace.

What is the expected result?

The game's still running

What happens instead?

[signal SIGSEGV: segmentation violation code=0x1 addr=0x48 pc=0x6b00d6]

Anything else you feel useful to add?

My system is Ubuntu 20.04.6 LTS with default GNOME shell. Seems the crash happens when the screen actually turns off because if I just quickly lock the screen and enter my password back, without the screen going off, it doesn't crash

I failed to reproduce the issue with Mint Linux + Cinnamon. I'll try another machine later.
