As for bumblebee, I wish I had a snapper image to fall back on (I stopped using btrfs) to see what changed. I suspect it’s linked to the recent gcc6 and glib updates, though I’m not sure.
Can you see if anything runs with optirun? Some things work for me.
There are reports of the problem also on the steam forum. It does appear that all the people having this problem are with openSUSE (Leap42.1 or TW). So it’s unknown who should make the fix.
