Please describe your issue in as much detail as possible:

When I start Dota 2 from Steam in Ubuntu Studio 24.04, it starts up, but then crashes soon after.

When it does crash, my ps utility stops working as it hangs when run, and strace shows it is failing too. This forces me to restart my computer when I start Dota 2.

I have installed Steam using sudo apt-get install. I have tried using flatpak and snap installations too and those have the same crashing issue.

Steps for reproducing this issue:

1. Install Ubuntu Studio 24.04
2. Install Steam & Dota 2
3. Update to latest graphics card drivers
4. It crashes soon after you start

• Sometimes it crashes immediately
• Sometimes it takes a minute
• Sometimes you can load a whole game then it crashes soon once it starts

Sounds similar to #2807

Try adding -threads 0 to Dota's launch options. While you're at it, you may also want to set LD_PRELOAD="" if you don't want a 10 FPS slideshow after 20 minutes of gameplay (ValveSoftware/steam-for-linux#11446).

Here are my launch options, that make the game somewhat playable:
LD_PRELOAD="" %command% -novid -threads 0 +fps_max_ui 20 +fps_max 60 +map_enable_portrait_worlds 0

Thank you for the launch options @rzaba0 . I tried them out (twice) and both times Dota 2 crashed & caused the issue with ps that I describe in the original post (which I since edited as of yesterdasy to add more context). I also tried out your launch options without -threads 0 and Dota 2 starts up, but crashes seconds after (demonstrating poor performance in those few seconds).
