    I just spent almost a day trying to solve this issue. Following this thread, I started by changing the blit type to never/always/auto without any success.

    My project is using unity 2018.2.5f1 + Lightweight renderer. Everything was looking fine until I added a hud camera with the clear flag to Depth only.

    Then, I installed and tried all the variants on 2018.2.12f1 and 2018.3.0b5. Same blackscreen.

    I started to mess around with every properties that seemed related. I've found that LightweightPipeline -> Render Scale is equal to 1 *AND* that LightweightPipeline -> Depth Texture is DISABLED, it fixes the black screen issue.

    I don't totally understand the internal issue here but it's a shame that the Render Scale property isn't working :( I was hoping to tweak this value a lot since our vuforia game is draining to much cpu and power.
