--- Comment #10 from Adam Jorgensen adam.jorgensen.za@gmail.com --- Okay, so I updated the 32-bit sabayon I use for performing chroot work stuff, installed Steam and then ran the application via the 32-bit chroot and the application works perfectly.
I guess it is thus likely that the sabayon multilibs are currently running a bit behind.
