Hrm, interesting. I don't have a Bigscreen Beyond 2 to test, but I'll give the current build a try in Steam VR again next time I boot into Windows. Thanks for giving it a try and the report!
I’ve encountered this issue too, so I played on the standalone Meta version when I tried out this game, but I think this is caused by checking dynamic resolution in project settings. Try unchecking it, and see if playing by Steam VR still causes that stretching issue.
