Yes, the current public beta is Steam only. I'm not sure there is going to be a non-Steam beta. Yes, of course, the final update will be available for all users...

Running the new Beta and updated last night to the 0.8 build through steam.

Screen seems to have a weird red banner now that pops up and disappears when you hover the mouse over menus.

It reappears and comes back when you move the pointer.

Same here. I’m also getting the intermittent red graphical band when moving the cursor over the menus in Build 1900.8. I’ve seen similar graphical glitches with some previous Public beta patches as well.
