I just checked and the walls seem to be working for me now. I also got an alert about resetting when I did so this time, so thank you for that. I understand accidentally uploading the wrong build. I setup some scripts to help warn me if debug is still enabled on the export versions after I had uploaded a debug build. We also always have at least 1 person do a quick play of the start after an upload, just to check for anything obvious. We'll see if someone can do another play of this version later this week.
The grid issue could be Linux or driver based. Here is what I see. This first is when stationary.
This one is after it settles a bit after moving. You can only faintly see the extra vertical lines, as it settled while I pressed to take the screenshot, but the extra horizontals ones are still clear.
