--- Comment #3 from Jacek Konieczny <jajcus at jajcus.net> ---
Ok, managed to check it right now:

> When the game freezes, if you do "strace -f -p PID", is the game still active?

Yes, shows a lot of I/O on some pipes and sockets.

> If you attach to it with Gdb, where it's stuck:
> $ gdb /proc/$(pidof KSP.x86_64)/exe $(pidof KSP.x86_64)
> (gdb) info threads

Maybe, I should try removing
'/home/users/jajcus/.local/share/Steam/ubuntu12_32/steam-runtime/amd64/usr/lib/x86_64-linux-gnu/libxcb.so.1',
in case libxcb from Steam Runtime is broken?
