📄 Description

With the default steam profile, steam runs fine, but several games (all running via proton) do not open or open to a black screen. Checking journalctl, each segfaulted with firejail reporting they tried to access syscall 101, which is ptrace.

Games: Twilight Struggle, ZeroK, Supreme Commander 2

Adding seccomp !ptrace or allow-debuggers seemed to fix the problem, and now the games run fine.

I added allow-debuggers to the profile, as I think that was the preferred method of allowing ptrace, but I can change it to seccomp !ptrace instead.

Just checked now, and seems like other people are having this problem: Issue 2860
