Still happening with `0.16.30`. Haven't encountered any other games with the issue.

I just tried standalone client (0.16.28) and it works. So clearly issue with Steam. It's something that updated in either system libs or the steam. Because I it was running just fine in steam the first day 0.16.28 came out.

I'm on Steam beta channel. I just tired running the game with overlay disabled in properties. Same thing.

I actually found this part in the logs interesting:

X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 20 (X_GetProperty)
Resource id in failed ...

Having similar issue with ArchLinux after system update.

Tested both 0.16.28 and 0.16.27. Both worked before.
