Hi
Just updated from 2018.2b8 to b9 with my mobile (Android) VR game.
First build shows black screen. No Unity splash screen, no 2D UI (I start in 2D) and no 3D.
However checking the logs, it’s working fine.
After experimentation in a vanilla project, it’s caused by the “Blit Type” value in Player Settings | Resolution and Presentation.
It was set to “Auto” after the move (from b8 to b9) and the same in a vanilla project.
Switching to “Always” fixes the problem. I tried “Never” and got the same black screen problem.
I’ve reported it as a bug to Unity along with a test project but, in case others run into this problem, I thought I’d report it here too.
I also tried disabling VR and trying however that’s giving even worse result – a SIGSEGV after the splash screen (even with “Always” blit?!):
I’m not going to investigate this part now but obviously that’s quite serious.
HTH.
I had the same issue (not VR). I got the black screen once blit type is never (or “auto” in case if you are using a native resolution, no MSAA and Colorspace is gamma).
This issue is reproducible in Unity 2018.1.6f1 as well and it’s very sad. This option (never) important if you want to increase the performance.
